Reading through a lot of the questions, particularly in the What is this forums, i found that some questions/problems were allready solved.
would it be possible to add an option for the poster to mark it as solved? with an icon or text perhaps?
I had it on one of my phpbb forums, where there was a support forum. mods and posters could then change the status of a question/problem, which was visible by a piece of text and colour.
just an idea ;-)
