  15. What else you can do • Send request to your server and return information in text,XML or JSON format. • Insert activity in users updates. • Use of AJAX. • Store information at Orkut server. • Fetch owner and his friends information.

  16. What you can’t do • Post scraps through your application. • Fetch personal information like phone number, birth date etc. • Communicate between different OpenSocial sites. • Any change at Orkut site. Application runs only at the space allocated to it e.g. profile view and container view. • Run exactly same application on all supported sites.
