Used to be that you could award points for folks answering your questions. I think the options were 50, 100, 200 and 500 points. But I can't see where or how to do this. Anyone know how or if it's still possible?
if your question is 3 days old then you can click on edit button in your question and then add a bounty. then it will apear in featured questions and the best answer will get the bounty.
All you need to know and more can be found in the FAQ
If your question doesn't get any answers for a few days, you can put a bounty on it. That's about it, I think.
