Something I figured out after a few visits here... some of the acronyms are underlined with a little dotted line. If you hover your cursor over them, it will tell you what it means. This works in both firefox and google chrome, not sure about other browsers.
Yep, that works too. So you can hover over things like PCC, FDA, HC, ECF, atty, VG, PG, and others and it'll define them for you.
