Right, here goes. I've had my domain registered with 123-reg on the basis that I heard they're good. BT on the other hand are offering me free hosting for 1 year on, what seems like, quite a good package. Apparently, according to BT, they need the domain transfering to them [BT] as part of this. This is free and 123 not BT will not charge me for this. But just how do I do it?
