QUESTION:
Is Mr. Flo's jurisdicion confined just to the "Guitar Central" forum or to all of the board?
Mr. Flo's jurisdiction right now is the Guitar Central forum. If Mr. Flo wants to handle other forums, that is also possible, but then again that's all up to Mr. Flo.
The next question I s'pose is what Mister Flo is supposed to do. (Hmmm "Mister Flo" sounds like "Master Po" from some old kung fu flick)
Forum moderators are limited to acting as a cheerleader/cop function - that is, if things get out of control, then the mod steps in. I would suggest sending a PM to the offending part or parties to get them in line. (and be nice but firm about it). A mod can also delete posts or threads that can be deemed offensive. Banning - well that's still to to the admin because you'll need access to the admin control panel for that. But the mod's responsibility is to recommend to the admin who should be banned.
On the more POSITIVE side - a forum mod is not expected to be a heavy-handed SOB. His role is to encourage forum participation, get the threads going, promote the forum in other areas (in othe rwords, invite people to login), and give ideas about how to make the forum a better place.
Overall - we expect the musician forums in general to be a place where people are comfortable in sharing ideas - in this case, ideas about guitars, guitar gear, and guitar-playing, and to keep that mood going, some idiot causing trouble by bad mouthing others is extremely counter productive. So that's the time the mod steps in, to clear the air and get the good vibes going again
Mister Flo was supposed to get all this in an off-line discussion, but since you asked....
