Okay, I'd be glad to help. I created the page microactivism (small case). Can you have a look to see if I got the jist of it? I didn't cite the Facebook page because I don't know which dictionary they pulled that from; otherwise, I would have cited the dictionary. I also didn't use the exact wording for this reason and because I didn't know whether that would be fair use or not, but I suspect not (IANAL).
