Well, it'd be the best way instead of parsing through a php file.
All you would need to do is access the mySQL database, get a list of all the member names (and any other details from the table(s)) and print it to a gridview or listbox or listview or something.

but, I'm at work right now. If I have some spare time or at lunch, maybe I'll get a chance to look at it before I go home even.

And I wish you guys did CoD4. lol. I've had CoD4 for PS3, but find it on PC much mroe enjoyable and just recently got it and wouldn't mind finding a clan. But oh well.
