I came across this site in another geocaching forum and thought that some of the Maine cachers would be interested.
It lets cachers verify that they have calculated coordinates for offset, puzzle, etc. caches without having to contact the owner. The cache site is Evince and the link is http://evince.locusprime.net/cgi-bin/index.cgi
The owner can have it either require exact coordinates or set a distance that is close. I think it is kind of neat if you want to set up a puzzle cache but dont want to answer the emails of "Are these the right numbers?".
