I've noticed a lot of "how to" things get endlessly reposted as the threads that contain them get buried in newer threads.
WHat about having a "white papers section" where "how to" things, ongoing research projects and whatnot get posted?
another forum that i browse occasionally (because of my involvement with FIRST) has a similar setup, and i think it would work well here:
