As a newbie on the job (and still learning my way around here as a mod), I too had the concern of always having the "moderator" title looming under my SN. I don't know if I'm still comfortable having it wherever I post on FT, but when only acting under official moderator business do I ever post a signature stating that I'm a moderator of a particular forum.

Perhaps it should be made a bit more clearer that moderators are moderators when a signature is placed under where they're posting?
