This document introduces and describes the various types of Internet services referred to in my faq. I broke it out of the faq file in order to streamline it and divide up the fuctions. The descriptions of services here are my own and are not official. You subscribe to a mailing list and are sent messages by email.
Mailing lists are the best way to automatically get the latest info.
With a digest you don't get the messages in real time, but you also don't get a lot of mailing list messages mixed in with your other mail. Not all lists offer digests. To subscribe, send mail to the subscription address and fill out the message appropriately. You can often send a help message to the same address. For lists run using listproc or listserv you usually give your real name after the list name when subscribing.
