i think it be a great idea to put in a invite option for coalitions that are created
That option already exists: open diplomacy, select a nation / player and send a message with invitation.
But I know, you probably want to be able to ping other players quickly with just one click - well, personally I am glad that this possibility does not exist, so that one will not be constantly spamed with impersonal inquiries.
Browser games are an ingenious business idea to lure out money -
- more or less cleverly camouflaged as a real game sometimes.
So beware of caltrops, spring-guns and booby traps.
