Yeah, that’s a bummer. rigmarole can correct me if I’m wrong, but I believe the forum limits editing until a user reaches a number of posts made or total time read to keep people linking to things and then changing the links later to something bad. Maybe you ran into this with just a draft saved?
Most browsers and webpages are better these days, but I’ve been burned multiple times (not here) writing something, hitting “Post”, and poof… it’s gone. I usually use Obsidian or a scratchpad app to write and then paste it into the forum box.
Once you are up to it😫, feel free to post your follow-up sync questions over there.
In using this “Forum” am I exercising basic Obsidian functionality or am I using a ‘Forum application’ whose functionality is separate from an appearance that is rooted in Obsidian templates?
Writing in Markdown will work in the forum, but Obsidian and the forum are completely separate. The forum runs on the https://www.discourse.org/ software.
