what if it is not an array. What if you just have a userid?

Well, you mean a single variable? Please post an examle :p

i mean in a php file i just thought off a number: 26. I then wanted to find out the corresponding username How?

I've just realised the functon you posted earlier is simply to transform the username into the musername, which contains the usergroup html markups.

There must be another function which does what you want, I'm sure. Go siffing through the function files :p

Oh joy, sounds like i have an interesting night a head of me. *sighs*. Oh well better go get some pop corn :p
