And by paid staff, I mean staff who are paid purely for forum related things like moderation or tech support. If you're running a hosting company or software development house, your staff are likely to be forum staff almost as a matter of course (with it not specifically being part of the job description). I have to be honest and say I probably wouldn't, even if it was a forum for a company I was involved with. Why pay money for a role that some people are willing to take for free and existing employees could probably do perfectly well anyway? Especially as it'd be a pretty empty, meaningless job if the forum wasn't super active and there was a whole deal to monitor (like on 99% of company and professional forums in existance).
