Uh, I already have 6 players and that's pretty much my upper limit. Will see how that goes for starters, but frankly, I'm not too keen having more than 6 players at the same time. If some player don't want to play in the long run, will consider replacing them, but for now, won't accept more player, sorry.
As for silent viewers... as long as they really are silent, I don't mind. In real life table, having non-players commenting on the action already tend to disturb the game, so on an online table, where things can already be quite confusing, having "guests" posting would just add to the confusion. So if you want to watch, it's fine, but once the game has started, I'll ask that you refrain to post there.
