So discourse now allows users to send incoming mail to simulate a mailing list. We would need to enable incoming mail for each category separately. I think the following approach would be best:
email@example.com: Support category
Additionally, we could also add a blanket category called
discuss or something and forward
firstname.lastname@example.org to that category. Admins would still be able to change the category of any of the new topics.
After we do this, we can send out a mailing list, twitter and blog post blast and phase out the mailing list.
