Dice Man, I'm not sure how to do that. I just had one of my computer savy friends do that for me and whenever I post a message it just shows up automatically. I wish I could you help you out, but I have no clue. Good Luck! ps, maybe dude can let you know how to do that?
If you click on "Edit Your Profile" in the upper right hand corner, you can add a signature. It is fully html compliant. that means that you can add a link, a picture, or just some text. WebDude once did a demonstration on how to do this. If you are having problems, try emailing him. Remember that any images used must be on the Web somehwhere.
