When entering an existing game, display a message so the user knows to proceed

[rupl]

Although the private URLs work great, I keep subconsciously looking for confirmation that I entered a valid URL before entering my name and hitting play/watch.

Maybe we could add a small confirmation message above the "login" that reassures the user they found the game they were looking for.

I was told "there is 1 other playing" when the other user was watching. This should say "X other participant(s)"
