Short sale help pretty please..

So I need some AR expert help..please :) Honestly, I haven't been working the sellers lately (just as they aren't the cards I've been dealt lately). However, for someone that has become a short sale expert, can you give me a quick run down of the procedure and complexity of working with banks. Also, I know its the golden question, but what are you advising your customers as far as their credit ratings?? Are many buyers settling with the banks or being put on a payment plan for the deficit? Thanks greatly in advance,
