    How to Add a Signature to a Gmail Account

    Are you tired of typing your name at the end of every email you send? Want to make your emails more professional looking, with links to your business websites and company logos? Gmail allows you to quickly add custom signatures to every email you send. You can add links, images, and completely change the formatting of the text. See Step 1 below to learn

    Adding a Basic Signature

    1. Open Gmail. Ensure that you are logged in with the address that you want to add a signature to.

    2. Open the Settings menu. Click the Gear icon in the upper-right corner of the window, and select Settings from the menu that appears.

    3. Find the Signature section. Scroll down the Settings menu until you find the Signature section. You will see a text box as well as a drop-down menu with your email address.

    4. Type your signature. You can type anything you'd like into the signature field, and use the text formatting tools to give your signature a custom look. Signatures commonly include your name, place of employment and title, and your contact information.

      • You can change the font, color, weight, and more using the text formatting tools. A signature should be easy to read and professional. A distracting signature will make you look less professional to the recipient.
    5. Add links to your signature. If you have other websites that you want to link to in your signature, you can add them by clicking the Link button at the top of the signature text field. It looks like a chain.

      • Clicking the Link button will open a new window. You can enter in the text that will be displayed for the link, as well as the actual address. You can also link to other email addresses.
    6. Add different signatures for different addresses. If you have multiple email addresses associated with your Gmail account, you can have different signatures for each one. Click the drop-down menu above the signature text field to choose which address you want to create a signature for.

    7. Choose where you want the signature to appear. Check the box beneath the signature text field to have the signature appear before any quoted replies. If you leave it unchecked, the signature will show up at the bottom of the message, beneath any quotes.


    Adding Images to Your Signature

    1. Upload your image to an image hosting service. If you want to include an image in your signature, the image will need to be available online so that it can be linked to. You cannot upload an image directly from your computer to Gmail to use in the signature.

    2. Copy the image URL. Once the image has been uploaded, you will need to copy the image's URL, or address. Depending on what image hosting site you are using, you may be given the URL when the image is uploaded. If not, you can right-click on your image and click "Copy image URL".

      • The image URL should end with the image's file type, such as ".jpg" or ".png".
    3. Add the image. Click the "Insert Image" button above the signature text field and new window will open. Paste the image URL into the field in the new window. If you paste the correct URL, you should see a preview of the image appear below the field. If no preview appears, then you likely did not copy the correct URL.

    4. Adjust the size. If you are using a large image, then it will likely take up too much space in your signature. After adding the image, click it in the signature text field to open the size options. At the bottom of the image, you can choose "Small", "Medium", "Large", and "Original Size". Pick a size that allows you to see the image without taking up too much space in the signature.

      • Since the image is being linked to and not actually included in the email, you don't have to worry about uploading it every time you send an email.
    5. Save the signature. Once you are happy with the way the signature looks, save your changes by clicking the Save button at the bottom of the Settings menu. Your emails will now include your new signature at the bottom.[1]

    Basic troubleshooting In school computer LAB

    * The Computer Won’t Start A computer that suddenly shuts off or has difficulty starting up could have a failing power supply. Check that the computer is plugged into the power point properly and, if that doesn’t work, test the power point with another working device to confirm whether or not there is adequate power.

    * The Screen is Blank If the computer is on but the screen is blank, there may be an issue with the connection between the computer and the screen. First, check to see if the monitor is plugged into a power point and that the connection between the monitor and computer hard drive is secure. If the problem is on a laptop, then you may need to get a professional to fix it as some of the internal wires may be worn.

    * Abnormally Functioning Operating System or Software If the operating system or other software is either unresponsive or is acting up, then try restarting your computer.

    * Ubuntu Won’t Boot If you are having troubles booting Ubuntu, then you may have to reinstall it with the Ubuntu DVD.

    * The Screen is Frozen When you computer freezes, you may have no other option than to reboot and risk losing any unsaved work. Freezes can be a sign of insufficient ram, registry conflicts, corrupt or missing files, or spyware. Press and hold the power button until the computer turns off, then restart it and get to work cleaning up the system so that it doesn’t freeze again.

    * Computer is Slow If your computer is slower than normal, you can often fix the problem simply by cleaning the hard disk of unwanted files.

    * Strange Noises A lot of noise coming from your computer is generally a sign of either hardware malfunction or a noisy fan. Hard drives often make noise just before they fail, so you may want to back up information just in case, and fans are very easy to replace.

    * Overheating If a computer case lacks a sufficient cooling system, then the computer’s components may start to generate excess heat during operation. To avoid your computer burning itself out, turn it off and let it rest if it’s getting hot. Additionally, you can check the fan to make sure it’s working properly.

    * Dropped Internet Connections Dropped Internet connections can be very frustrating. Often the problem is simple and may be caused by a bad cable or phone line, which is easy to fix.

    * Reboot your computer. Turn your computer off, let it sit for two minutes, and reboot it. Sometimes one command of the hundreds a computer executes every second can cause corrupted memory or other temporary unexplainable problems. Rebooting will clear out all the gremlins and gives everything a fresh-start.
