I've had really great answers on this forum from knowledgeable and helpful people. That's why I'm always advertising for you guys (no stock though). :-)
In that sense I think something about the forum should be improved, namely the [closed] tag. On stackoverflow "[closed]" means that the question was improper/vague/homework, etc. So, it comes with a very negative connotation.
It would be great if it can be replaced by a big "Okay!" sign, or by other wording like [perfect answer], or [answer accepted].
