I'll try posting this suggestion here, since the suggestions I posted in the Feedback section don't look as if there are being seen to.
I have NOT been able to locate anywhere the system requirements of Foldit. The program works fine on my computer (apart from the occasional bugs appearing), but I thought that Foldit's system requirements should be posted somewhere on either the Foldit website (perhaps the FAQ page), or the official Wiki article, so people interested in playing the game can see whether or not their system can support it.
Primary factors include (but not limited to) CPU, RAM, Video Graphics, Disk Space.
Optionally Operating Systems (even though this is fairly evident on the home page), and the fact that it isn't yet available in a 64-bit version.
