@Mux Suggestion

With leasing rate fluctuating so heavily, as person leasing rig, we need lot of time spent on setting appropriate price so that it is competitive as well as reflect current pricing.
So I will like you to implement functionality where leasing person can set price to (X +/- Y) or (Z +-Y)
where variable X is current highest price quoted
Z is mean price of rigs open for renting or already been rented
Y is variable which person wants to set (e.g + 0.001 BTC or - .002 BTC per MH/day)
And we should also be able to set lowest value so that it doesn't go below that.
This may seem bit complicated but will be very easy to implement in site since you are already sorting rigs by rent price and will be easy to figure out highest price and mean price.
