Recently I've been posting my games on some other adult games forums to help get them out there. I have found that forums are currently the best way to find an audience for adult games, and while the AIF community still definitely has many good reasons to exist, and it's where my personal heart is, it's also good to draw in players who don't know about us. So anyway, here's a little review of my experiences with other active forums:
is currently probably the most useful forum for drumming up interest, even in older
topics. I don't see heaps of chatter over there, so it's mostly a lurker
forum, but they do seem to take an interest in free, Western games. I
think this forum has a requirement that you post a number of posts
before you can do some things, however.
Legend of Krystal Forum
This a relatively useful and active forum for AIF style stuff, surprisingly, or at least I've found it is for my games. The only inconvenience here is that while you're new to the forum you have to wait for posts to be individually approved by a moderator (including edits), so that makes it annoying if you want to go back and edit your first post, answer a bug issue or post about an update.
This forum shows a decent amount of interest (though not as much as might be expected). They do have a good 'showcase' forum for authors to post their work.
I think this forum is mostly interested in professional games translated from Japan, there is much less interest in Western games.
The Undertow Club
This forum, formerly known as Hentai Ryona, doesn't have particularly restrictive rules but only generates moderate interest.
The Shark's Lagoon
At one point this was a very important site for AIF but Shark is difficult to deal with and the forum's rules have grown hostile to developers. While there is a decent community here I'm not sure I would necessarily recommend the forum to anyone any more.
I don't know if this list is comprehensive, but it's all I've really found in terms of large, active adult games communities out there. Are there any more I've missed? Is there anything I should mention in this brief review of the other forums?
