            > Highly recommended!

            Does the email discussion lists have the ability to show it's discussion on a web page? and can there be a login required, or do we have to build a login ourselves?

            We have a RSS authority site and want to either bring our discussion out in the open or have it behind a required login, we have not decided yet.

            We may be a little behind the scenes on our web capibilities but we are trying.
