Will a dude get banned if he hosts an etourney even when hes not staff
-----
or part of teh event squad i dunno :/

Probably not, unless you pretend to be a member of the Event Squad. I don't see a problem with calling your room ETourney if that's what you mean, just make sure it doesn't get to the point of staff impersonation.

There's calling your room etourney and then there's globalling the room and saying it's an etourney.

Both probably shouldn't be done. For the first one, you are confusing anyone who stumbles on it, and you are also taking up the 'etourney' name for a server, which could have been used by a member of the ES. For globalling, I would expect some sort of punishment since ETourneys usually mean people will be getting ST if they win, which a normal user can't provide, therefore you are misleading them. Could even probably be chalked up to staff impersonation, not of a member, but of being a member, but I'm not too sure.

you can host a TOURNEY but Etourneys are mostly reserved for ES hosting (or so i believe). i'd go with duck's suggestion and stay away from calling it an "Etourney"
