Sorry about that. I moved my website about 8 months ago, and tried to let people
know, but some links never get fixed. If any of you know a good way to gather
emails for the people with broken links on their sites, let me know.

I was in contact with a guy a few years ago that wanted to do the exact same

relatively straightforward. I wouldn't mind doing some development work if you
