my-net-minder.pl is similar to the Netmind URL-Minder service (now called Mind-it), but lets you take parts of the page out with a regexp so lame things like SSI counters don’t cause you to get notifications every time the counter ticks over. It uses a MD5 checksum of the cut-down page as a basis for comparison. Freeware.
