This is kind of both a bug and a suggestion but I'll post it here.
This little window right here is kind of not that visible. It only shows on the lobby listing page and not the lobby page itself. Also I believe it should be much more prominent than a little black box in the top right. Possibly a dialogue box / modal window (I think that's what they're called) that you have to click past to get into the lobby.
In general this should be able to help us host lobbies in Australia without euros or Americans joining. I've tried, and generally you just spend the whole time kicking people during the set up phase.
