If you're new to the EA Forum, consider using this thread to introduce yourself!
You could talk about how you found effective altruism, what causes you work on and care about, or personal details that aren't EA-related at all.
(You can also put this info into your Forum bio.)
If you have something to share that doesn't feel like a full post, add it here!
(You can also create a Shortform post.)
Open threads are also a place to share good news, big or small. See this post for ideas.
Hello, Willa! I've activated the Markdown Editor for you — not sure why it wasn't working. (I'm the lead moderator/admin here.)
There's a lot of stuff on the Forum. Perhaps the best way to start out is to browse the top posts of all time and read whatever looks interesting. I don't love all the posts on that list, but they're a reasonable sample of the topics that get a lot of interest here.
The natural book recommendation would be Toby Ord's The Precipice if you haven't read it yet; I've liked the bits I've read, and reviews from outside of EA have been solid.
