Is there any imageboard-like forum software?
I mean something like imageboard, but with users and forum features (like PMs, reputation and stuff).
If you could imagine something like Facebook with some text formatting (BBCode is preferred, but Markdown and others will go) and other basic imageboard features as self-hostable software, it would be something I'm looking for.
I don't care about its system requirements, I have a good webhotel in trusted hosting company, and if it doesn't run here, I can host it in my own physical server.
