I've updated the groups system, as described here.
The big changes are:
- "Newbie" is now called "Contributor"
- "Regular" is now called "Established Contributor"
- "VIP" is now called "Distinguished Contributor"
- There's a new, higher tier of VIP, called Top Contributor.
- The requirements for VIP have been increased slightly.
I've written up a short FAQ here, which describes exactly what is needed to get to get to each level.
More changes are likely to come over the next week.
Specifically, I still want to sort out the colors for various special cases, such as moderated accounts, banned accounts, and our helpers.
