I don't know if this is supported in V3, but i would like to suggest.
You can chat with one person through Rmail. You can chat with everyone through the ShoutBox. But wouldn't be nice if you could do a 3-way or 4-way chat? This is great for Kir's Quest team-ups, a group planning a Res user-created event(such as b-day party for someone on Res, etc., or just a couple of best friends wanting to talk! Your conversations wouldn't get cluttered and confuzed by other users talking on the same box. :)
Also, if you are over like, 15 or something, couldn't you do video chats with your best buddies that you know in real life? Of course, you would get a video chat request, and you would choose to accept or not. For safety, if you're under 15, you would have to have a parent's permission to be able to video chat with a specific user. Other users could be blocked, again for safety.
Please post saying support for both, only support for one and which one, and please, i want to know why/why not. thanks!
