A link to an information page describing how people obtain GPUCoins would definitely be useful.

How do you expect someone who hears about the cheaps GPUs will be able to make a purchase if they have no idea what GPUCoins are or where to get them?

I for one would get frustrated and forget about the site.

I believe right now that the difficulty of obtaining GPUCoins and lack of information is one of the big hurdles for this site, much more than the prices.
