Thank you for the feedback and suggestions you provided. We will keep them in consideration while continuously improving Wolfram Community.

I believe Tingting's point — if not, it is my point — is that the post one is replying to moves well out of sight. Often, I want to reread something to make sure I've got it right. On a long thread, it's hard to manage scrolling up and down.

The fact that you can't use emojis here is not a serious problem. The fact that emoji-postings fail with a "The message system is temporarily unavailable" error is a concern. Vague error messages that don't point to the [simple] solution are problematic. There no way to measure, but I'm certain more than a handful of newbies have punted when they got that :( message.

Tingting, you're currently participating in a Wolfram U course. All things equal, I think that Wolfram U courses would be far better off if Discourse were being used for their messaging. They're easier to use, easier to navigate, they scale pretty well, and -- most important -- emojis are available. ;) Newbies are grappling with brand-new concepts in a Wolfram U course. The way they converse with instructors and each other should be as easy as possible. Many of them are already familiar with Discourse and similar systems. Are all things equal? I cannot tell. I have asked Stephen about that in one of his live q&a sessions; he ignored my question. Perhaps he had more important questions to deal with.

Interesting. I don't think that trolling would be an inherent problem in a private Discord group for a Wolfram U course. I don't think trolling would be a problem if the entirety of the Wolfram Community's discussions were ported over to a Discord server. OTOH, I do think trying Discord with a few Wolfram U courses as an experiment would be a good way to start.

There is zero chance that our intro to Calc course would move to Discord. That would make no sense; it would be planned in advance -- probably >6 months in advance. We really don't get a vote in this. Maybe the first overture would be for Wolfram U to do a survey of its students and see what they think about the idea. I fondly hope that this is something @Jamie Peterson (Director of Wolfram U) would consider in the future. You're the only participant in these forums that I've ever conversed about their community software with. I happened out of random chance to stumble on the discussion you created.

I just don't know how much friction there is to staying with the Wolfram Community forums. Is that an important product for WR -- a selling point to companies to use their software? I don't know. I don't think so, but I could be mistaken.
