Hey! I've been having some trouble with one of the players in my group lately. I run a game at my school for eight people, and things can get pretty chaotic. I don't know a lot of the people there outside of the game, including this guy. This guy speaks up a lot, which is fine, but lately he's been telling other players what to do. I've had to warn him to not interrupt other players, or talk during other player's turns, or to try and stop other players from doing what they want to do, all several times. He's also talked to me about running his own game after my campaign is finished, which is again fine. But he's also talked about excluding specific players in our group, including myself, from this new game of his. He literally made a list of everyone he wanted in his game, and said something along the lines of "you'll manage on your own" about the rest of us. I'm not really sure what to do. Were this game held at my home I'd have suspended him from the game already, or even just made a bigger stink about it. But seeing as this game is part of a larger club, and I don't know my players outside of the game, I feel awkward doing anything about it. I'm worried I'll seem overaggressive and get in trouble with the host, or alienate my other players.
Advice is appreciated. Thank you.

Have you talked to the host? I've had this problem in similar (non D&D) clubs and that seems to always help. Hosts have to have some measure of negotiation skills, or they couldn't host. The first thing I'd do is ask for the host's input.
I think Rudoplh has the best place to start. You already addressed things between the person at the table, and the host seems like the next person to start the discussion with. I would hate to let them take over their own table and pick and chose the people they will then subject to their current style. The other option is to say ok, and then you get to have your own group that they aren't a part of.
