nope...it doesn't work...
I have the webmaster showing as a moderator in all of boards I have and I can't get him off...it does work though, with a recent new board I have created. In this board I can assign the webmaster as a moderator and get him off it wiht no probs...but it doesn't work the way you suggested, which I believe to be the proper way...
Should I try with phpMyAdmin and get him off from there?
I don't know...any idea?
