info about forensic nursing/ SANE?

Hello all. I am one of the many thinking about going into nursing. These boards have been very helpful so far but I was wondering if anyone here is a SANE or a forensic nurse... do you like it? what is it like? what is the difference between a forensic nurse and a SANE? what is the special educational preparations for this career? do you need a separate degree? ...or if anyone can direct somewhere to find answers to these questions. Thanks a bunch. -ashley
