Hey guys,
I have just realised how to give out popularity, you have already found out but if you haven't please follow the simple steps below.
1) Look through the posts and when you find an interesting one click on it. Or if you have a problem about something and someone answers it on a forum post, then click on it.
2) if this helps and you think it deserves popularity aka REP then click the plus button found on the right hand side of the post.
If this helped or you didn't no how click the + buttom:D
Thanks RawZa
