Wow, some nice ideas in here! :oo
Maybe some words why the groups have been changed: The general idea behind the new groups wasn't to indicate who posts the mosts but it was developed to give those WHO are active around here some "home feelings".
Actually the steps between the group levels are a bit bigger than most of you might think, this way it won't become too easy for trolls to "quickpost" themselves into better positions.
Also the new ranks are meant as some kind of honor to those who get them, if someone is patient enough to post more than 1000 times here he surely isn't a troll because NO troll has enough patience to post that much.
About the "point idea":
This sounds really great, but I can also see some problems there, the very first is that I'm not sure if we can use any computer system for this, finally we will have to put the points one get down manually which isn't the savest system... ;) BUT we surely will think and talk about this idea, simply because the general thought behind it really appeals to me! (If we introduce it you, SuvieD, surely will get some points for the idea! ;))
