Thanks! Seems to work now. Maybe you could do the same with the "bogus messages" for chgrp?
Code:
[17:00:23] [L] site chgrp /Default.User user
[17:00:24] [L] 200-Group 'user' has been successfully added to Default.User.
[17:00:24] [L] 500 chgrp: Directory/File already exists.
Haven't used this new function enough to spot other things that might be wrong, but I will keep you posted.
