My first thought was a combination of Dizkus and the mail2forum functionality. Disadvantages:
- half of the Yahoo subscribers must be persuaded to register on the website
- Dizkus is more a forum module than a listserv module and is probably to overwhelming for the majority of the target audience
- Attachements, if possible at all, will be per thread in stead of per post
Second though is to create a simple listserv module that allows subscribing and un-subscribing without registering as a user on the site. This is going to be more work though.
Any thoughts, hints, similar solutions?
