This has been brought up before, multiple times I believe. Unfortunately no competitor or substitute to the Arc forum has become popular, so it looks like we're stuck with it for the near future.
Right now it seems to me that the best alternative to the Arc forum would be convore[1], which ar uses[2]. It has some problems, though. In particular I remember it being quite difficult to paste in code snippets. That would be problematic for a forum related to Arc. Any other suggestions?
