what happened?

The Way VB works is when anyone (Members or guest) View the board and are looking around. It will log them as "Online"

When they close there Browser it will still show them as Online for the amount of time that Zelaron has specified.

Its like this. You go on Zelaron and are looking around the site and posting, having fun Then you have to hmm do the dishes and you close the browser and get offline. Well, it will show you online for the amount that WW or Chruser decides it to be till you are finally shown Offline.
