For a line of dashes like "-------", most screen readers can recognize repeating characters, so that string gets read for me as "7 dash". If using an <hr> element, then there is no ambiguity about what it means.
Might work for you too.
Edit: Also, do you MUD?
Then Empire Mud, but I left due to disagreements with the admin. I loved the concept but it didn't really have the playerbase to support it.
More recently, I was on Procedural Realms. But I was affected by 3 separate instances of data corruption / loss, the last of which resulted in an unplanned pwipe since there were no offsite backups and the drive on the server failed. Years of progress gone due to lack of backups, so I'm never going back.
Ever since, I've been trying to find something else. Perhaps I'm just getting older but I don't have the patience to grind that I once had, which rules out most hack and slash muds. These days, I prefer something with interesting quests, places to explore and mechanics.
What muds do you play?
Is reading the books required for enjoyment? I haven't read anything from the Discworld series.
There's also a newbie group chat where you can ask for help, the syntax is 'newbie' followed by your message. It'll go away once you get too many levels in your skills.
A drawback with Ankh-Morpork is that it has cops, they might interfere if you decide to attack something that isn't a rat or cockroach or somesuch, but if you get caught and put in jail you'll eventually be released. Getting killed is a bit worse, you either waste your experience points by getting a raise from an NPC, or send a message to a particular type of priest that can resurrect you.
And how painful is reading emails? HTML email is notoriously limited compared to HTML (and CSS) in the browser, but it's pretty hard to add structure to a plain text email too. How annoying is it when I do so using e.g. a "line" made out of repeated dashes?
