You could always post on /p/. The criteria seems to be fairly low- mainly that the board has a functioning BO who checks in periodically and/or that people are semi-actively using the board (if it's not a bunker). I mean, at least in /doll/, /islam/, and /fa/'s case it looks like they maybe have one discussion per month at best, and /p/ doesn't look far off. If you post in threads for boards you like, I know a lot of anons do look at the webring widget and it does bump the board there. That's the only reason I remember to go visit /kind/ half the time.
