Discourse software is primitive because it is buggy, has no undo feature, and no speller. About one year ago I switched from Firefox Internet browser to Chrome browser. When I tried to use the Discourse, it automatically created new profile/identity. For several months I had two profiles. Then Discourse went haywire and eventually blocked my access to the old profile. Sometimes I type new post for a few minutes, make a mistake, and lose the entire post because there is no way to undo the mistakes.
The old Rhino forum was posted here:
It was better than Discourse. Now it is gone without a trace. All the wisdom posted on the old forum has been lost.
By the way, Discourse website is here: https://meta.discourse.org/
