I posted this awhile back, but I guess no one knew... and I still don't.
If you could help me out here, I would
really appreciate it.
The regular Avatar hack:
When the avatar is supposed to show up under the name of the poster on a post, it does so, but the image code source says "0:0" where it should have the name of the chosen avatar - like, "leo.gif" or whatever. When I go back to my own profile to take a look at what avatar I have, it shows "Previous" highlighted. "Previous" has the value of "0:0" (wherever that came from), and all the other avatars have the correct value.
