I didn't know about this until today. Just mentioning as I sold some of mine @ a rate of 7100... well below what I've seen people offering on here, and without any trust/escrow hassles.

In Ripple: open your wallet -> advanced tab -> trade -> change issuer to rvYAfWj5gh67oV6fW32ZzP3Aw4Eubs59B (bitstamp) -> sell your XRP and get your BTC -> send BTC to the address you get from bitstamp
There is no need to grant trust to bitstamp.

Now what? How do I get my BTC out of ripple? Edit: So now I go to bitstamp, open an account (or login) and then click on "Deposit" and then on "Ripple" and then follow the instructions to send the btc to bitstamp within ripple.
