Probably a good idea, but absolutely belongs in About This Message Board and not buried in this thread. We have a partial FAQ for the board in ATMB. We don’t have a general one I guess.
We do maintain one for “How to Moderate on Discourse”. @engineer_comp_geek started it and we’ve both added to it. It is pretty helpful. One in general besides the glossary would probably be handy. Especially as much of the Glossary is somewhat dated.
There was one for computer questions, that was unpinned as it was so dated.
Maybe start the discussion in About This Message Board and mention what you think belongs there.
I think a link to Discourse New User Tips and Tricks should be prominent.
There use to be an easy shortcut to all the keyboard shortcuts. That disappeared in one of the Discourse updates. Apparently Shift? does the trick.
