So, if you set the subsequent posts to unlisted, and someone from the public clicks on the first post, they will see the whole thread?

Also, I type it up in Mastodon until I near the limit, then copy to Notepad, then ditto for 2nd post, etc., then when I'm at the end I can add the right numbering (e.g. 1/9), and copy them from Notepad back to Mastodon and post them. This also helps with getting the right char count for each, cos of things like URLs only counting for 23 chars, etc.
