I am a new user, but if I had the time this would be a good first plug-in write for me. Unfortunately, I don’t have the time. Sooo, if anyone does have the time and interest, a very useful plug-in would place a button at the bottom of every post that says something like “Report Abuse”. If someone sees spam in a post or foul language, etc., they click on this link and a report is sent to the moderator.
This is used in many large forums I use and could help control misuse of a bbPress forum.
