Author's Message - I try to maintain my codes and data as up-to-date as possible. So if you are using any of my codes or data it is important that you tell me, so that I can put you on my distribution list to inform you of updates. This is a FREE!!! Service that I provide to users of my codes or data. I've tried to make this as easy as possible for you - PLEASE take a moment to e.mail me redcullen1@comcast.net and tell me what you are using - it's as simple as that.

WARNING - If you do not inform me, any of my codes and data that you are using will quickly be out-of-date, and you will have nobody to blame but yourself. So again, PLEASE contact me redcullen1@comcast.net and tell me what you are using.

User feedback is VERY IMPORTANT! Does this site meet your needs? If not, why not?

Please let me know redcullen1@comcast.net and I'll try to update this site to better meet your needs.
