I don't know how useful this is, but for your interest I'm attaching the IRB protocol and description, as well as the approved welcome screen, registration page, and recruitment email (which we sent to several email lists, including this one, back in March).
You can see the live click-through registration at http://www.majorminer.com/info/intro .. then click on the "register" link.
It seemed pretty easy to get this past the Columbia IRB, once we assured them it was fully anonymous. But maybe they were easy on us because we're only engineers...
