Hi,
I had a look but due to the nature of my search I am not getting very specific results 
I wonder if anyone can help. I would like to know if there is any way within Yii or without that would let me know if a user is currently online? like in facebook.
So if i display a list of users it would tell me what users are logged in or not.
Am I missing something obvious on this one?
Cheers for any help
