When I create a game, I then send email to the friends that I want to join me in the game. In this email, I give them the game # and the password.
If would be nice if CC would generate a link to a newly created game that could be placed in an email so that joiners would simply have to click the link to be sent to the specific game page. The password shouldn't be embedded in that URL, probably.
Unless there's a way to have PMs forwarded to email, this probably won't be very effective for me. Then it will take even longer to get my friends into a game I start because I'll have to wait for them to go to CC randomly and see their PM.
