Well, here's my alter-ego! I've lost a few teeth and my hair has gotten darker, but hey - it's a dog-eat-dog world out there!
Avatars are little pictures that represent your "alter ego" - you can see mine under the Q&A section of the public forum - look under the "email delay" topic. I also have a special topic about avatars for members only - see the "General Discussions" forum. You can easily add yours by logging in, going to the discussion forum, and click "my profile" and you can upload a small gif or jpg. The file must not be larger than 100 X 100. If you need help, post to the forum for questions.
Feel free to upload your avatar and show it off here!
