was last edited in 2011 and could have more info about being removed from the main single-player list. I'm not sure about how being removed from the main list affected the gold star thing too.

If you go to recent changes, almost all substantial changes are made to Idle pages. Idle-related pages are edited frequently, at least compared to others.
Checking the wiki right now, it isn't as "terribly outdated" as I thought it was, but it still has a general "dead" feeling. If you click "Random page" you have a good chance of landing on a 3-line page that doesn't help very much and was last edited in 2011.
I want to get started on how to actually participate in a wiki, as I don't have much past experience. Where to start?
