How much activity do you expect out of your staff? How much do you think is fair?
I think that depends on how much other work they are doing. If there is a lot of "behind-the-scenes" work that they're doing on the forum or they are doing a lot of advertising for the forum, then I'll let them slack off a bit on being active on the community. If they aren't busy doing other things, then I do expect them to be active. I won't expect them to make 100 posts a day on the forum but I do like to see them make a presence within the community.
