We say it a lot, but in honor of Earth Day, we’ll say it again: repair is green! Fixing stuff keeps it out of landfills and keeps green in your wallet where it belongs.

It’s also a great day to share your repair know-how with the rest of the earth. Today marks the two-year anniversary of the day all our repair guides became wiki-editable and we launched our guide-creation software, Dozuki, on iFixit.com. We now have over 3,000 user-submitted repair guides. Is there something you know how to fix that doesn’t already have a guide on our site? Make one! With your help, we can fix the world, one device at a time.
