Shout out to the Stanford Online Accessibility Program website. It's the most coherent resource I've found that really explains all sorts of context around accessible websites. Not just "here are some tools" but "here is how to think critically about your users and make a site that works for everyone".

@darius Extremely relevant to me as I just got off a phone interview for an accessibility position.
Specifically I found them via their excellent page on screen reader testing. They do a great job talking about the different kinds of screen reader users (not all are blind!) and their particular needs, as well as emphasizing that accessibility is not completely or even mostly about screen readers, though obviously they are a big part of it.
Friend Camp features several modifications that were requested by our users.
If you want decent privacy (the info doesn't leave this server), the only way to do that is to set your account to private, only accept friend requests from other friend.camp users, and only ever @ mention other friend.camp users. Once you start talking to people on other servers, all bets are off. Any private message you send to someone on another server could be looked at by the admin of a different server. This is kind of like email: if you are on a private email server, and you send an unencrypted email to a gmail account, congrats, Google now has the content of that email. But also, you do this every day, so, hey. The internet!
