Hi
Since underleying motivation tool in forums is the "points", I think this suggestion will at least be acceptable.
Since some contributors forget to reward points, there may be a new utility providing posters other than who opened the thread, to report it is solved and a content manager marks the question as solved after inspection. The inspection may be just to look for a post saying "Thanks. Question is solved" or something like that.
Is that possible?
