Forum:Showing online/offline

Is it possible to show a user as being logged on at the time? I mean, if they are logged on, is there a way to put "Online" or "Offline" if otherwise? 08:03, August 13, 2011 (UTC)
 * Not unless they've set up a template or something that they edit when they're on or offline - you could encourage users who want to tell people this to log into chat or something when they're on --  Random Time  08:06, August 13, 2011 (UTC)
