The way a mailing list works, is that you subscribe to be part of the list. We'll say there are 100 other members on this list. If you send an e-mail to the list, it is received by all 100 people on it. When one of them sends a message, you and the other members receive it. By subscribing to a list that has 100 Lotus Esprit owners, you have the collective knowledge of 100 Esprit owner/enthusiasts to draw from. If you have a question, chances are that someone on the list can answer it. Once you buy a Lotus, hopefully, at some point, you can help the discussions by answering questions as well. Expect to get between 10 and 40 mails a day when you're subscribed to a list.
