How can i know weather whose online in orkut?
In orkut, after login, in your friends list, you can find the most recent online friends from top left to right in a first row. But that doesn't guarantee that the friend is online now. In order to find out the friends online, it better to look for those small circle below your friends. If its green then that means your friend is online in GTalk. If its red, then he/she is Busy and if he is offline, the circle color is off.





But these small circle will be shown for only those friends who has got Google Account i.e. GMail Account.
Reply:recent friends photos will be displayed on ur home page...





green circle will be there only when they open gtalk
Reply:when u open your orkut homepage, in friend list it shows around 9 friend's photo in friendlist out of all.


these 9 people are the most recent online peoples in your friendlist.


and the one whose photo is 1st or 2nd, is the most current online friend of user.





one more thing, if he is online in GTALK then a red/green/orange coloured dot will be there just under his photo.(this must be known to all..)
