I remember now, the malware section was one place we tried it out.
By "we" I mean Chris, once when he'd just been made a moderator (before malware specialists, I believe) and again, later on, with the malware specialists helping.
By that, you can see that even with a team doing it in just one board, it wasn't workable.
patio's point is also valid - especially in the malware section, where some people tend to get infected over and over again.
