I think maybe he doesn't quite grasp wat admin rights are and what they are FOR.
Stealthmonkey, normally you don't need any admin rights to race on a public server, nor to "talk" (I suppose you mean chat, right?). The only thing you need admin rights for are things like kicking/banning users from the server, changing different server settings and stuff like that. You know... to admin a server. So... unless you want to kick/ban people you have no need whatsoever of admin rights.
If other people do have "the rights" then that's because it is their server, or they were given "the rights" by the owner of the server. I hope this clears things up a bit for you.
