Looks like a craigslist adult services ad, except you're wanting bitcoins, and not a man to...

Why don't you just use an exchange? Britcoin is a good one.

I am buying and selling bitcoins for cash in london. Click my webiste in my profile if you want to exchange.

Has Ubitex implemented time limits on sell offers or other protections against the wild price fluctuations yet? I'd feel uncomfortable promising to sell BTC for some amount that seems reasonable now if I have to remember to keep going back to adjust my offer whenever the market rates change.
