I used to write Poser tutorials for "3D Artist" magazine, and got a copy of 7.2 with one of the issues containing an article of mine.  I only just installed it yesterday, so I'm in the same boat as the OP!  It looks terrifying, but I'm looking forward to being able to do some modelling and rendering with Carrara, hopefully I'll get good enough to post some pics here along with my Poser work!
