Does anyone suspect that
Clipse and pirateat40 might have the same business model? They both sell bitcoins locally, and they both pay extra for people to mine for them. Neither of them give away much more information than that (understandably).
Hmm....

Ever considered that Clipse's so-called "pool" ( not a pool 100% because all normal pools publish found blocks - it is a proxy like ABCPool ) is just diverting to GPUMAX and he is taking a big fat 30% cut from everybody ?
No wonder you cannot use GPUMAX through his pool ...
The myth of selling BTC to fools locally is laughable. Nobody is stupid to pay more for BTC than market rate I would believe.
