1. I agree that that would be nice.
2. Such sections probably wouldn’t be updated often
enough to motivate people to check it themselves.
3. Trolls would not use a section designated for them, and this whole “bored” is just that. I think threads generally get at least as much attention as they deserve.
4/5. The general inability to contact another poster about something that isn’t a thread topic without posting in a thread is annoying. However, I don’t know if bbPress even
supports private messages or profile messages, and I highly
doubt the mods want the burden of deciding whether specific
private communications are safe.
Perhaps there should be a stickied thread for non-topical messages,
and everyone would check to see if anyone had
left a message for them every once in a while.
