The "Online Now" notification shows up on a profile when a user logs in and gets into our system.
The "Online Now" will go away the moment they log off.
However, if for example they close the ChristianDatingForFree.com website window by clicking the X at the top right- without Logging Off first- then we can have no way of knowing that they wanted to log off.
In this case, the "Online Now" will continue to appear for 1 hour. At that point, since there is no activity by the member, the user will be logged off.
So essentially, there are certain circumstances where it will appear that the user has the "Online Now" notification on their profile but they are not actually online.

Most of the time though, people who have the "Online Notification" are actually logged in and online.
