For search and threaded visibility, it would be useful to have these discussions happen on the forums (created a category, let's see if we use it:
https://discussion.fedoraproject.org/c/containers) and then be put into the issue tracker on Pagure where applicable.
Since both Pagure and Discourse work with FAS, noone needs to create any extra accounts. I'm up for it, let's see what we end up using. If we do want some engagement within Fedora from outside the world of people who know how to handle mailing lists, this is a good way to start. I have to just remind everyone here that there are plenty of smart people willing to get started with open source who have no experience with mailing lists and IRC, where a forum with usability and structure really provides some initial help that shouldn't be underestimated.
