Take this FWIW because none of this is set in stone but this thread will probably be moot over the next few months. The trend is to not log people out unless they physically log out by killing the session (even if you close the browser), almost all social media sites operate this way as well as some other dating sites. We will likely move in that direction. That being said "online now" will probably fade to black as we replace it with "available to chat" which is the main purpose of the online indicator. This way unless you indicate that you are available to chat there is nothing to show that you are online other than time stamps on certain activities.
With that I am moving this to Community Help.
I sign in at work just about everyday because my home computer is out for repair right now. I am able to come and go at my computer so I sometimes I will leave it up and just minimize CM. I have been teased by another that they want a job where I work so they can be online alot like I am. So... creepy or not I am here! LOL By the way my first date was with a scammer just looking for some physical action and perhaps money. FYI. But I know there are many good ones out there.......
