It has become tenfold easier to get started in recent months, thanks to the release of an open source pool - found here. You can get going from a cold start to being fully set up and 'mining' in less than half an hour. A video tutorial on that page will walk you through the steps.

Best part: this pool charges zero fees. The only thing you pay for is the transaction fee to withdraw your GRC, and that it utterly negligible.
