SFN user groups and their significances?

[THX-1138]

I haven't posted a lot, but I noticed recently that somewhere along the line my profile page says Group: Senior Members.

 

Where did that come from? What's a 'senior member, what the flying moose ears did I do to become one, and what other groups are there on SFN and what do they mean?

 

Thanks..

Members automatically become Senior Members after 30 posts. Senior Members get to do a few things that ordinary members can't, such as send more private messages or post status updates on their profile. Mostly this is to stop spammers, which often register and post spam to their profiles without ever posting on the forums, so we never notice them.

 

There aren't any other groups for members apart from Resident Experts and the moderator staff.
