I guess I could have called this "YAAP" because it is Yet Another Avatar Plugin, but hey what's in a name right? This plugin is a knockoff of AstonishMe's AM Custom Profile plugin. What it does is allow your bloggers to upload an avatar and create a signature block. The admin has to allow "user directories" for it to work, then each post by the blogger will show their avatar and signature block. Mostly good for multi-user blogs?
