uhhhhhh is there a guide on how to use lists on mastodon (in particular the web app)? it took me like ten minutes of poking around to figure out how to even make one (there isn't just an option on a user profile to "add to list," you have to go through the "getting started" tab thing). mostly I just want to know (a) if my lists and their content are visible to the public and (b) if other users are notified and/or can find out that I added them to a list
