Instead Of Chating On Profiles which earns u AP there could be a Chating station where you can know when there offline you just simply click next to there name (If online) start a conversation cause they won't be able to see that you have writen on there profile can they
I wonder if you checked the "Common suggestions"....
Anyway: Chat is a nono*. There is plenty of unofficial chatsites that relates to AG. I use this, and all we need is simply to remember it, open it when you log on AG, and wait for your friends to do the same.
*there was one, it got removed due to people spamming and flaming. Seemingly some people are unable to act their age.
Plenty of AG users seem to be starting to become aware of that one~ So if you're not on your own comp or am not allowed to download IM programs (though you can actually log on to several via your browser), that's a good way to go. Just make your friends aware of the room and that you will be there.
