Hi,

You can import mailing list posts using the MailArc plugin. It can import posts by connecting to a pop account and downloading the mail off of a pop server. So as long as your existing posts are available via pop, you should be able to import it.

Gossamer List is quite different though. It provides a way to send out one-way announcement style mailings. It has the ability to create, import and manage subscriber lists, and then send out mailings to those lists. It provides the admin the ability to see all sent mailings. It does not provide two way communication like some mailing list software like Majordomo. It's meant as a one-way announcement tool.

Hope this helps,

Alex
