I really do like to fix broken links, but its a monumental job. Websites change links willy-nilly all the time, and its very hard to keep up with.
You can help a lot by just reporting when you find a link that does not work.
Please note what page of Build-It-Solar you were on, and the name of the link that is not working -- just pasting it into the email is fine.
Send reports of broken links to Broken Links...
Thank You!
