I've made an imageboard. There's an instance running here:http://board.seize.ch/
Right now it's just a place for some of my friends to post anime pics. You're welcome to do so, if you'd like.
When I can afford a server I'm planning to host a more "serious" instance.
I don't really know what the focus will be, but I want to have a videogames board where we choose two or three games a month (mostly old ones) for people to play and discuss, so as not to have many small, short-lived threads discussing a single game, to avoid general threads the likes of which you always see on most videogame boards, and to enjoy and discuss some lesser known games.
If the game has multiplayer I could also host the server for a month, and then decide whether to keep it alive some more if people are having fun with it.
If you are interested and feel like there's a board topic that no currently alive imageboard handles well, I'm open to suggestions.
