ULX Max Groups

What is the maximum amount of groups I can create?

I don’t think there is a maximum.

I wouldn’t recommend using ULX though, as it uses questionable workarounds which are no longer relevant in the current version of GMod (and haven’t been relevant since 26/10/2012).

Try Xandaros’ Evolve, Prefanatic’s Exsto or Chessnut’s Moderator.
