I was going to sign up to the forums originally but I'll just add here.
In response to Guest_Dave who posted in your mining contracts thread:
am I missing something... £400 a month for 1Ghash? I could expect half a bitcoin per day from 1ghash, which would mean at current exchange rate I earn about £90 a month??
For £400 I can buy an entire PC with about 400Mhash, so after 3 months I am doing better than your mining contract...
And another thing... for £400 I can simply buy 66 bitcoins from an exchange site... which is about 4 times more than I get in a month from your mining contract... Why would I do this?
I think he deserves some BTC for pointing out this massive flaw in your pricing. How did you come to these prices?
