[Carnage]

Well, i'm admin/coder on a fairly large board. (i'm taking large as it needs its own dedicated server)

The way we try to work it is somethign like this:

6 admins; In theory we all have a responsibility such as coding, or dealing with problem members.
5 Smods; some look after a section of the board each, some just float between sections helping out where needed.
about 50 mods; They do most of the day to day grunt work in their indervidual forums.

We've got a custom built warnings system which helps alot with dealing with threads + posts, we also have a forum for each level of staff and a warnigns forum to deposit trash in. Again in theory there should be regular meetings help on Irc between various groups of mods/smods/admins to discuss new policys and other such occurances.
