My guess that it would be an opt in and for fannish comms, I'm not sure that would actually come into play (i.e.: again, why pay for what you can get for free elsewhere. Some people might float it but I think it wuld likely not be worth their while at some point.)

On one hand it could be seen as a 'zine mentality -- but the reason I think it wouldn't actually fly fannishly is more because if fans have to pay for service, they tend to be demanding about the level. We don't get into so many intra-fannish rows about entitlement for nothing. *g*
