This website has all the documents of the text about what is going to be posted on the wall, what is currently posted on the wall, or what was posted on the wall, in case you wanted help on the issues within LAUSD that you could write on your post-it, if you strongly feel like it should be fixed.
If you're afraid of being detained by ICE or can't come outside for some other reason, then you could either ship the post-it to me, and I could put it on the poster for you, or you could have someone else write it down for you.
