The wizard diceroller is what I use if i really need one, its simple and got everything you need, I think there were some kind of wierd roll it couldn't do, but it covers just about all the gamemechanical dicerolls for almost any game.

did som editing, its a LONG list with description now, but just skip whatever doesnt seem interessting.

I'm gonna see if i can add more content to this group, like discussions and similar. Do want to have a detailed description of what each RP is about but i can just go back and edit my own post in "system interesst"
