it's surprising that there is still an issue with mailing list and forum split. that's am issue we already had 30 years ago. and i thought by now it's a solved problem. google groups solved it for example. is there no FOSS platform out there that does it too?
the platform i am working on could do it too, but i thought it's not worth the effort because there should be enough alternatives. am i wrong? what stops fedora from using a platform that integrates email and forums?
