I can see what Happy is aiming at. It's not hard locatingsomeone with the gender of your interest, but then your gender has to match that person's interest as well, of course. For straight situations, this is the case more often than not, so you can just check out a few people and usually come in luck. For gay situations this is much less often the case. (Especially for males? Females seem to dig it both ways more often than males do, but that's just my perception, could be incorrect.)
But seperating it over so many boards seems to be getting cluttered. If someone's looking for a male, does that mean male character, male player, both? For story ideas I think putting tags in like (Looking for male player) or (Looking for female character) would be somewhat effective without being overly clutterive.
Besides the story ideas, it might help to have a list of members with not only their own gender, but also the gender they're interested in. Though if you'd add that, you might as well add if people are interested in dom/neutral/sub, freeform/system, solo/group, etc... Not really feasable on this forum without resorting to new plugins, but from what I heared about Vekseid's plans with ons/offs built into profile, etc, it might be feasable after the upgrade.
