I dunno if this can be implemented but on of the forums(of shurtugal.com) I have visited there is a sort of money earning feature where each post you earn money and with this money you can buy stuff.It is a little complicated which is why I don't think it can be added to this site.I suggest you visit this site(go to forums and in that go to store for a detailed explanation on this topic)to get an idea as to what I am talking about.
Again,I know this sort of thing cannot be created on this site but I just thought it was a cool feature.
