if im being a moron, please excuse me. 

is there a way to allow a player to destroy his or her own stuff, but NOT allow anyone else authed on the TC? i am using "AuthorizedDamage" but dont want anyone else to be able to auth and then destroy. 

its a creative server, and id rather not get into any greifing issues. (havent had them yet)

im not having any issues yet, but i want to give the ability to test a base, but protect those just on for some creative action.  

thanks!
