I can see Nim: https://hacklines.com/en?tags=Nim
The Nim Forum is a staple of Nim. I'd rather spend time improving it than switching to Discourse, are there features of Discourse that you think might make it more accessible?
There are also other places to discuss Nim which are more accessible to people: https://nim-lang.org/community.html
I hope the Nim ecosystem comes up with it's own (genuinely free) alternatives - eventually even to GitHub, Linux, and the browser stack. ;)
A long time ago I suggested that to attract new developers a mailing list would be ideal. Following the forum is just inconvenient for me. My email client is vastly superior than any forum or rss interface. I find discourse much worse in term of user interface than nim-forum (at least this forum is simple and clean).
FIY, a long time ago I started a one-way mirror of all discussions though gmane. You can follow all discussions happening here using your favorite nntp client and pointing it to: nntp://news.gmane.org/gmane.comp.lang.nim.general
You can subscribe to a read-only feed by using nim-general+subscribe@thregr.org as well. This is how I follow this forum.
Sadly, gmane has switched over to new maintainers a long time ago, and part of the web interface is no longer functional. I was about to submit a link to the gmane archive when it suddenly ceased to work. But the nntp backend is still up and running.
I wished the forum itself would provide a true bidirectional mail interface.
wavexx: for some time the forum was able to mirror posts to dedicated mailing list. Unfortunately the SMTP integration has been shut down.
There was also an attempt at receiving messages from the mlist using POP - see https://github.com/nim-lang/nimforum
Perhaps you might want to mirror the forum using an external tool?
And I would like to add that I would be fine if the mailing list address is added somewhere in the official nim site and/or to change it (for example to use a nim-lang.org subdomain). The GMane address is also public for anybody to use and thus can be listed publicly.
As I stated, it's read-only. You still have to use the forum to post.
