Thanks cl_out. That helped. I don't think that there's anyplace that actually explains any of these groups and I'm not about to search for threads so here is my take on them:

Site Staff: These are the people who do all of the work for the site and do the updates, etc.

Senior Site Staff: Do the same work as Site Staff, but more so because they tell the Site Staff what needs to be done. Senior Site Staff also have Mod status in the Site Staff Forums... or maybe all Site Staff have this privilege in the SS Forums...not too sure.

Recognized Members: Members who have done some constructive work for the site or have created contests, etc. Contrary to some beliefs, members are not RMed just because they are poplular.

Administrators: Basically do all of the technical work that goes into running the site, etc. and they are the ones that make the rules and police the board.

Cid's Knights: Same as the Administrators except for the technical work.

Eizon Overseers: I have no clue.
