How do i opt for ''no network'' on Facebook please and how do i delete friends on Orkut?

Go to the Network link on top of the page in facebook.


Do Join a Network and select NONE from the list.





If you have alreadty joined a network, they will be displayed on this page and you can select "Leave This Network" link, in front of them.





On Orkut, go to the Friends link on the top. Select the person you want to remove, and click on the EDIT button in front. then from the options listed, click the DELETE button.





Hope it helps.
