Ok, I did not think about doing this as a category vs separate forum. Would there any problem with having separate users, or not linking mailing list email to account here?
Having a new archive for mailing list and separating tagging here can be done in parallel. This is more technical, or about forum management. The structuring of tagging discussions is more conceptual and intertwined.
The conversation of migrating or bridging mailing lists to this forum hasn’t been advanced much because 100% of the technical time is now focused on the old forum migration and then will be focused on the Help & Support site transition.
Some people have already expressed their interest in moving from a mailing list to here, and we have started experimenting with enabling the creation of new topics by email in #general and #site-feedback categories, so people can use the forum as a mailing list.
Message mirroring or migration is a separate conversation that would need to happen if it’s a need for people (instead of leaving the mailing list archive and start fresh here).
