Etiquette for joining a game

Hi,

What's the etiquette for joining a game? Say you're in the lobby and someone starts a (non-private) game. Is it OK to start playing one of the islands uninvited? What if the game is, say, 10% done - is it OK to join the game then?

Any Suggestion Would be appreciate.

I didn't find right solution on the internet.
