Another useful tip: if you're not sure whether something is worthy of putting on the page, or just want to mention something about a page (inaccurate data, speculation, etc), put a note in the Discussion tab/"Talk:" page.
Not a big deal right now (and it hasn't really happened yet), but once the wiki becomes more populated it's preferred to keep the main pages clean. Feel free to add content to places you think needs it, even if you have a couple blanks that need filling in, but try to keep the other stuff in the Talk pages.
