EC, you should really post your challenge with URestrict in the URestrict thread.
ULX has options for some tool control, but, they aren't based on group, only per user or per everyone (including admins), and thanks to the hard work Jay is putting into URestrict, we aren't going to be upgrading the ulx tool commands.
It wouldn't surprise me if we were to eventually remove them.
We (Team Ulysses) have been pointing everyone towards URestrict for the access you're wanting to control.
Jay's been working hard on a rewrite of the code base of URestrict...how long since you last used it, and, were you running all the latest SVN versions of ULib and URestrict?
I understand if you don't want to run SVN (our beta code), but, it really is meant to do what you're trying to do.
Otherwise, see the ulx help command
