Thread questions

I created a thread a couple of days ago and received some help - now I have some questions about general forum use. 1) I see that somehow the thread was rated and there are some stars by it. What does this mean and who rated it? 2) Should I resolve the thread when I am finished with it? 3) Does the person who helped me accumultae points or anything like that?

You should see a little box on the right labelled "rate this thread". Any member can rate a thread. If your problem is solved a final post saying so is good form. But someone else may still have a followup question, so in general we do not close old threads. And we do not have an automated point system here.
