For all that still intrested in this. I am still working on this mod, and is almost done with it.
Logged Out (Guest) "avatar is a default for guest accounts"

Logged In (Member) "your own member avatar and profile info"

I am going to remove forum stats and poster hall of fame from guest portion, and put something esle. Not sure what yet thou. May be just expand the log In Registration area, or make a quick registration feature there.
If you have any suggestion or comments let me know and I will mark them in my idea file in my brain.
To Do List:
- Hardcode files changed to language file
- Clean up the look on "Logged in" portion
- Remove Forum Stats and Poster Hall of Fame from "Guest" portion and figure out something esle for that area.
- Possible make this SSI intergrated for use around other parts of the site.
- Thinking of making more then one version for diffrent type of use. IE: Focus on recent post, or User Login, Etc...
- Make mod file for YaBB Pak and Boarmod mod.
- Release a beta to beta testers.
