Ok, just wanted to know if there existed something in xep-0060 that I could use. So if I want to do it in-band how would one do it? The only way I could think of is the following: Subscriber -> Server - Sends a subscription message Server -> Subscriber - Send a presence subscription message Subscriber -> Server - Answer the presence subscription message Server -> Subscriber - Answer the subscription message. But I have no idea if that is a good way or not. / Emil
