This should be a good question to look into. Lets say I open up a few topics and all have like 150-400 points. And everyone replys with there help on it.
But I never closed the question and did not give the points to either one or too persons that helped me.
There should be a e-mail reminder send to that user saying( remember you ask a question but you never closed your topic and never rewarded the points to the person(s) that gave the best help he can give) Please click here to close and reward the points to the helpers)
Or the topic be auto closed in 60 days and the points be shares to all people that reply. 150 and theres 10 people reply so they get like 15 points each.
