Does the integrated facebook chat support group chat? I want to switch to WP8 from Android but I've come to use the Facebook Messenger app a lot, it is basically the only app I really 'need' currently. I use group chats extensively to organise things with friends etc and have basically got rid of the need to sms unless it is urgent. I believe that you can only message people over facebook if they're online, so I assume this isn't possible.
If not, are there at least notifications from the facebook app for when I do receive a message from one of these chats so that I can use the app/browser to reply?
The messenger app on iOS and Android really is fantastic, it's amazing it actually comes from facebook.
