I have a built in ranking system on these boards depending on your post count. Here is how I have it set up so far:
1 post = New Member
50 posts = Experienced Member
100 posts = Advanced Member
500 posts = Professional
1000 posts = Uber Member
Now I realize that these are all pretty basic and lame. So I am open to suggestions on what you guys think they should be!
EDIT: also depending on the rank you get +1 CSS image under your profile.
