We already tag questions with “Solved” and also I’ve seen [Solved] being added as a prefix to the subject of the thread.

But closing a question for further replies I don’t think is a good idea …

There are some discussions on improving the point scoring system, like allowing user to “thank this user” for the best reply … but I think that is something for the future :) Also, one question could have more than one correct answer.

Yes. I agree once question could have more than one correct answer. May be we can vote for correct or most appropriate answers.

Q&A forum features is on the long range target list, it’s quite a bit of work to make a proper Q&A system, just look at all the work that went into http://stackoverflow.com/ [stackoverflow.com]. So once we have progressed on our other feature requests, and gotten some more people on board [developer.qt.nokia.com], it’s definitely something we want to do.

That’s Nice.
