On our GEclan rolepaly server, every single user is able to spawn from a huge aresenal of css weapons and random stuff under a Weapons tab, how do i stop this?
Thanks in advance 
Get an admin mod like ASSmod or ULX to restrict weapons, or edit the lua yourself by changing
SWEP.AdminSpawnable = False into SWEP.AdminSpawnable = True
DarkRP restricts the guns on it’s own. ASSmod would cause problems itself with the guns. You need to make sure you remove the weapon restriction plugin. ULX doesn’t come with any weapon restriction by default, so you shouldn’t have any problems with ULX.
As for the editing of the LUA, that isn’t necessary for DarkRP.
DarkRP has an admin only weapons function you can activate with rp_adminsweps 1 in the console.
