This is an odd policy - I ought to start a thread "introduce yourself here five times". I also noted there is no email verification on the site. Alternately, send .001BTC low priority to the forum to be a full member (i.e. If you can get a bitfaucet payment and send it to the forum, your not a retard), but that's probably not something easy to add to simple machines forum.
Sorry i did not read all of the posts. here is my two cents... .001 with any kind of gpu is still faly easy so that would not help also because of things like bit faucet it would need to be > .01. sorry IMO email works well most of the time, if thats not good enough then fix the chapta out of 7 ocr programs i tried 5 of them got it right the first time.
