Unfortunately, bi_Mellisa, short of bringing back the Miss FreeOnes Contest, I really don't think there's much of anything that can be done to increase the OCSM activity. And that's not happening anytime soon.
Actually, it's not like there isn't an influx of new OCSMs. We do get new ones coming in. The problem is that they just don't stick around. And when you think about it, can you blame them? There is just too much of an overabundance of trolls and riffraff in general around the forums. It's hard for the OCSMs to find something else, some other attribute about the forums to neutralize that negative aspect.
