Rod,
In the little box above the forum's pages you have a "welcome message". In that box is your personal control panel.
Click on
User CP link and you'll find boxes to the left of the screen.
Scroll down and click on Edit Signature. Once there you can enter a signature line that you want to show up each time you post. :smoke:
As far as an avatar, you would do the same as with the signature. Only the avatar has to meet size requirements and an address to a hosting website/computer is needed.
I hope that helps?
Regards,
Ed
