It's supposed to be a whitelist...

You can always Ban people, which is in itself a kind-of blacklist. I don't see why restrict server access to non-admin, and blocking people from a SteamGroup would be dumb since they can simply leave it. (why a blacklist ?)

But yeah since the code could be almost the same that could be doable, but I don't see the point...

EDIT : Changed OnClientPostAdminCheck to OnClientAuthorized. Released 1.0.1. Thanks Franc1sco.

RE-EDIT : I also realized using SteamGroups would be a breach (people could still download; since the check isn't instant (you need to query Valve servers) ). But I do plan on adding them.
