I wouldn't necessarily call them staffs, but they are part of the team. Anyway.
Ever wonder of having welcome committe? I'm not sure if anyone have mentioned this, but I do apologize. Anyway, I was thinking Welcoming Committee would help the community (I guess) and basically help the new comers. Their job is basically simple, trust me. Just give the links the that are worth the read and be on the way, or just give them the hello.
I'm not sure if would find this...unnecessary, but I think it's cool. A welcoming committee can be quite helpful when it comes to new comers. ^^
