Actually, in your profile, put the blogg addy in under the URL, it should link right to your name again.
The squares are for no logical reason, apparently. The more you post, the more you get. Boo’s up to 5, tho Alex thought there were only 4.
You’ll also go:
New Member - up to 25 posts
Jr. Member - up to 50 posts
Member - up to 100 posts
Senior Member - up to 500 posts
(dunno what’s after that)
I may have the post count off, but I think that’s it, off the top of my head.
