There! I got the scripts to send out the License Key information. I got around having to mark the file “in use” by using two files - one to be read in, and the other to be output. Much cleaner, very fast, and little chance of problems. I also handled several error conditions: no name, no e-mail address, bad e-mail address and undeliverable e-mail address. Looks good too.
Here’s a really nice and comprehensive site all about genealogy and genealogy software for the MacIntosh: MacGenealogy.org. I added it to my Genealogy Software Links page.
