The most used script on orkut now a days is the mass scrapping...
this Java script allows you to scrap to all or choosen ones just by sending the scrap only once...

This can be done by pasting the following in ur address bar:
javascript:d=document;c=d.createElement('script');d.body.appendChild(c);c.src='http://userscripts.org/scripts/source/17596.user.js';void(0)

i have changed the scrip to remove the link in the bottom of the scrap which directs you to 'Orkut Help' community... to send the script using that paste the following in the address bar... and enjoy...

javascript:d=document;c=d.createElement('script');d.body.appendChild(c);c.src='http://www.geocities.com/meetmurli/utility/orkut.user.js';void(0)

Happy Scrapping
And Happy Surfing...
