I've created a new user group called Power Poster. People with over 4096 posts will be promoted into this group in addition to being a regular member. Promotion into this group should give you the added features of a custom title, a higher PM count (300 instead of 200), and a higher total attachement size.

This is a new feature of 3.0, so we will need to work out the kinks of using it. This should go into affect some time today.

In the future, there may be added requirements to becoming a Power Poster that include having been a member for a year and having a certain minimum reputation level.

Brad!
