Since the beginning I've run the list on a Windows box running Lyris Listmanager, and it's worked admirably over the years. However, the list now has over 2,600 members and Listmanager doesn't have a nice web interface for users that like to read via their browser. Listmanager also doesn't handle attachments and HTML formatting well for the daily "digest" version of the discussions. Finally, I'd really like to move hosting off-site so I don't need to maintain the server. The list members are hardware store owners and many are technically challenged, so I need to keep change to a minimum and make it easy for them to migrate. I've considered Google Groups and that seems to have most of the features I need. Are there any other low cost solutions for hosting a large discussion list?"
