Mailing lists are discussion groups for various topics. You need to subscribe to a mailing list to send and receive email from the list. See the mailing list section of the EFF's Extended Guide to the Internet for background information.
In the beginning, there was only the Coins list. The traffic isn't as heavy these days, but the list still has many knowledgeable and experienced members. See the Coins List FAQ and the Origins of the Coins List for more information about the list. See the Coins ftp site for the archives of the list.
