I created a new “they/them” badge. It can be used as a title (as you can see next to my name currently). I tried to use this genderless icon from font-awesome but it didn’t quite take.
Ideally, everyone would be granted this badge (or have a way to immediately claim it) but it looks like right now we need to manually grant them. I granted them to the people who I know of using they/them pronouns in this community, if you’d like the badge added you can send a PM to me or post on this thread. Once you have the badge, you can set it as your title in your user settings.
