I was just wondering if there was a way to find out how many of the variations in Unearthed Arcana can be used in other sources. I have a friend working on his own campaign setting that I think would make good use of some of the rules like the weapon groups, but I don't want to suggest he make the change if it could cause problems for him.
I know the SRD contains OGL material released by Wizards, but I haven't seen any alternate material like the weapon groups or spell points in it.
