My head is spinning! [Big Grin] I just sat here for the past 15 minutes pressing enter (debugging your code) to figure it out. So simple, yet BRILLIANT! You veterans never cease to amaze me! Sure beats the hell out of comparing every item in the array!

Final time on 422 (of 4592) groups, containing +3700 users (of 30000), Captured 574 users in 1Min 28secs. Not bad!

(IsInArray took twice as long)

Thanks!
