Email worked for me (gmail), but went to spam folder.  I'm really liking this service.  My rig rented out in less than an hour.

Lots of room for improvements and I see this service really taking off.  Some ideas:

Would really like to see the average spot price in btc/mh/day at which people have rented in the last 1h/8h/24h period.  Trending analysis can tell the buyer whether they should rent at a particular rig or not.

For rig owners: dynamic rates that follow the spot price +- a certain % with a floor price.

For rig owners: reputation system so buyers know the best rig operators for uptime, promised vs. real hash rates, etc.

For buyers: Mass buy option to purchase blocks of X Mhash, and this gets split up amongst X rigs.

Mux, you have created something great here.  Hats off.  I truly wish you the best of success with this project.  Is it your full time job?  If not, would you like it to be?
