"biking on the cheap"

Yes, it's kind of hidden, but we do have a wiki.  Besides hosting various organizational docs, the wiki also contains cycling info, some C-U specific, some good for anywhere. 

My favorite are the links collected under "Advice - Biking on the Cheap."  There you'll find links to instructions for all sorts of DIY bike projects, like making your own LED lights, fenders, panniers, studded tires, messenger bags, repair stands, and even porter racks, such as this one from bikecommuters.com:
