Dani- I think it would be a good idea to further explain reputation to new members. There are always so many threads started because people do not understand how it works. Most recently, this one: http://www.daniweb.com/forums/thread108977.html
It also took me a while before I figured out what was going on.. I think if you send them an introductory pm explaining how the reputation works (or if you already do, then think about making the message more understandable :)). This would save us time from having to explain to every new member via threads.
