OK, so under 'Users Online' it will say 'X Guests, X Users' and sometimes followed by (X Hidden). When you click on this it takes you to a page called "Who's Online" where you can see what everyone is viewing or posting in (under the 'Action' heading). I enjoy this feature because I've found all sorts of older, interesting topics. Anyway, when I'm not logged in I can see what almost everyone is doing (more on 'almost' later). When I'm not logged in, the action of a User will sometimes say Nothing, or Nothing You Can See. I know this means that they're either on the Private or Mod only forums, but sometimes it will say this next to a Guests name. What's going on here? Also, what does it mean when it says 'X Hidden'? Can anyone go incognito or Mods only? And, what's the point of doing so?
If all this is Topsecret OC.net stuff, I'll understand...
