Then here you go. The first point is to get good scores on your tests.
By the way. I use the same upvote system as @meesterboom (I think it's kinda smart and fair for everyone). He checks who upvoted the post and then upvotes back. What do you think about it?
Does that mean that if I upvote his post he will upvote my post in return?
Nah. When you upvote a post and leave a normal comment (not spam). Your comment gets upvoted. As simple as that. I think it's kinda fair.
That system sounds good. Rewarding normal people is a nice gesture I must say.
