If you downloaded the code and find it useful, I would be happy to put ypur name on my distribution list so that you will receive any future updates. Just e-mail me at firstname.lastname@example.org and I will add you to the list. Please put GEODESY somewhere in the subject line and mention that you would like to be added to the distribution list. The current version of the code is 0.92. I will send eric the latest updates as well in hopes he will post it. The code bundle is currently a 22.5kB zip file.
