How can I help?
best least effortful way to help is to go through the references and sprinkle them on the appropriate page(s), striking them off from here as you go along so we know they are out there (eventually somebody will nuke them completely off from here too, presumably).
More complicated stuff can be done also, of course. You can go through the articles in Category:Social justice, if none of the stuff on the to-do list is appropriate for you. If you are a FB user, we also have a group where we discuss stuff, but it's not really required as everything is cross-posted to here.
