Great Idea, Ive already sent a card from my Ego to my Self. I second the request for sending "special occasion" requests. Also how about international mailings and mass mailings, I have lots of family in Germany and they need christmas cards/thankyou cards.. and I am the lazy type so only 20% of my family gets a card, this would help lots

Also in your Proof email it is not apparent whether I need to take any action if there are no issues, wording changes perhaps? Maybe also on SendWrite "stationary"?
