A reminder, or in case there are still people here who haven’t seen it:
(1) If you type ? while viewing posts you get a pop-up screen listing a bunch of basic things you can do and keyboard short-cuts to do those things. Press ESC to close it.
(2) Keep an eye on the two forums “Site Feedback” and ATMB. They are full of threads with people asking all their Discourse questions and people answering them.
(3) In particular, take a look at GreysonCarlisle’s thread, “We’re All Here. Now What? (Basic Tutorial)” which gives a good beginner’s guide (more than a “Basic Tutorial” I think) and begins with a Table of Contents so you can find stuff. I’ve asked TubaDiva to make a sticky out of it. This will be a good thread to bookmark.
