Groups

Hi. I've got a problem. On my forum, I want to have 3 groups (for now): Administrators, Global moderators and Section moderators. And all groups that are shown on the forum are Administrators and Moderators (only Moderators, not section or global moderators). And to these groups I've set colors:

Admins - blue, Global moderators - orange and Section moderators - green.

And the forum shows me Admins green and Moderators orange

And yet one problem: How can I create a points system? I mean, someone's got 50 posts, and he's got a rank ABC. Then he's got 100 posts and he's got a rank DEF.

Thanks for answers.

And, one question: Why all the topics in FAQ give me "topic does not exist"?

Answwer me please I cannot wait
