ok, this might sound really stupid, but I'm totally a laymen when it comes to computers:o in my User CP i see some things called Reputation Points. what are they and how do I get them?

You can read about them here (http://www.evboard.com/faq.php?s=&do=search&q=reputation+system&match=all&titlesonly=0) ;)

a, ok thank you! now I understood the whole point of it :D

How many rep points do I have to get before I have another green dot?

It's a mystery! http://dhammaseeker.com/smileys/lock.gif
