You get a view of who is online and what they are viewing (or PM'ing). I've never used this as a villager, but I was paranoid as all get-out about this while I was a converted alien in the one game where I've played a bad guy.
Hopefully people are not taking this as an opportunity to use this feature ... I'm put it out there with the idea of full disclosure in terms of site features that can be twisted for WW. It was mentioned in one of my early WW threads. If we are putting together some kind of a code of conduct then I would strongly suggest that the use of this link is discouraged.
