I've been hearing some folks have been having a rough go with getting pictures to work as their signatures, so here are the steps to get yours working!!
1. At the top of the page there is a series of links you can click on, click on "Profile"
2. Next click on the link "Preferences"
3. Make sure you have "Yes" checked for the following two options: "Always attach my signature:" and "Always allow HTML:"
4. Click "Save" at the bottom.
5. Then click on the link at the top that says "Signature"
6. In the text block you can post the link to your image, please don't have too many images and no longer than 600 pixels and no higher than 300 pixels. That makes for slow loading for our dial-up users and if much bigger they will distort the board. You will have had to load your picture of a hosting site, such as Photobucket or Img Shack. When you copy the link make sure it has the image tags in it ( the image tags look like this, but without the spaces: [ IMG ]

7. You can then preview your signature.
8. Once happy with your signature you can click the "Save" button.
