Splitting a site into two parts

What are the benefits of a SSO environment like that? What are the drawbacks?

I don’t think there are any users on both lists other than me. They were separate Mailman sites for many years, and most of the users are still primarily email based.

Even the need to have separate email addresses to post via email to each category within that community is confusing to some of them, but I don’t see a way around that. I’m encouraging them to use the web interface, but maybe 5% do, 3 months after changeover.

My goal is to expand participation by having both communities web-searchable and readable. It seems to me like keeping them separate might work better for attracting those who want to discuss team X but not team Y.

I’m not in a major hurry, the summer is the slow time for a college sports oriented list, things will start to pick up in August when fall football practice opens. So I’ve got time to think through which approach is better for the communities.
