Yeah that's always just been an e-fed thing as far as I've seen from day 1. In the IWA (play by mail game) we could type stuff up to mail them and it could include other people. All the e-feds I've been in though have all had the same rule about not using other handlers' characters without permission. Once you have permission from them, it's fine.

When I attacked Chris Jericho with Scott Steiner in my RP, I think I beat him down on with a steel pipe or something like that. lol I definitely learned very quickly not to do that.
