Hello Gene, > subscribe sensors gene.heskett at verizon.net There is no automated subscription mechanism for our mailing list. We can add you manually if you want. However, please note that you don't need to be subscribed to post. What's more, the list is intended for developpers, not users, so you may reconsider your request. -- Jean Delvare http://www.ensicaen.ismra.fr/~delvare/
