I second (third?) Hans' suggestion. I would like to add that I can see how Stackexchange-like functionality would help me solve issues.
Furthermore, if there were a way to clean up threads (option for the OP to hide irrelevant parts of the thread? hide answers to subanswers by defailt?) where offtopic exchanges make it difficult to follow the relevant parts of the conversation, that would be awesome.
Edit: Duh, posting only works when you allow cookies. I had cookies temporarily disabled.
