For threads where people have raised problems, and members have helped solve the problems, there should be some way of knowing if the problem was solved, and what the solution was (apart from reading it that is) as some threads go on a bit.

There should be a quick way of jumping to the thread(s) that solved the issue, and what actions the user took. I it wouldn't take people long to click an icon or something to indicate which was the thread that did it, and hopefully it would stop people raising the same problem loads of times.
