33 edits later and I think I am done with this. Unless there are outstanding grammatical issues I have no intention on tightening up the language further and bumping this topic since other posts deserve their time in the limelight as well.
I would still like to know what i am doing wrong with the table of contents. Could any @moderators please look at my code and figure it out? The last post I submitted has a URL to the article @nam1962 linked me (which was split off into its own topic about root part size) that shows a functional example but my issue may be due to Discourse meta using a later version of the software or deep linking is disabled.
In hindsight, some of those edits were from moderators but I wasn’t fussed about that when I made this post. Apologies to @moderators for constantly pinging them but I still need their help.
