Have you ever considered having a forum for people who speak different languages such as french of german. In my experience these are used, not as much as the rest of the forum but it does give a place for the people who otherwise may illegible posts in the other sections, i could help with the french one if you were interested, just an idea.
Correct, but because it is viewed all around the world english may be a second langauge for some people and therefore they may wish to discuss things in their own languages where they can fully understand what is being said.
Its just an idea but i take it your not interested?
have you considered enabling auto-prune for the request section? threads could be deleted automatically 30 days or so after the last reply...just a suggestion, it's something I've seen at other forums with request sections, and I think it makes sense
