One problem is the way AChat is describing itself on their website:Downlaod the game, choose your gender, create an avi, invite people to have funThat's what I did on my first day too - I invited girls to have fun. I didn't even know about "cold invites". My luck was, that some started talking to me and that I like to talk too
Maybe a button, similar like busy-state: Accepting cold invites/not acceptingIf you accept, it means cold invites can be sent and you can agree or disagree. If you don't accept, they can't be sent to you
