though I did not find this feature much useful, still I gave it a try. Immediately after hitting the ‘events’ button on the left sidebar of my homepage, I got a form to fill and I did so by entering one of my friend’s birth day and also invited some of my friends too, to attend the event. Guess all the invitees have got an invitation and have an option either to accept, reject or choose the option ‘may be attending’ for the invitation sent to them.
Well many things done and said, but it matter not how much features Orkut introduces, but what matters is how useful are those feature..? You too give it a try and let us know, personally how useful did you find this feature.
