You can delete friends from your list my simply clicking on ’personalize my page’. All editing options are available to you - even the help section is helpful ;)
You can also use the ’who’s in’ feature which allows you to invite people from your hotmail,yahoo or outlook email addresses. The site has been made easy for people to navigate, even the not so internet savvy people. I have seen alot of my friends who stay in mumbai on this site as well. Got me connected to alot of friends from school I havent seen for a while since I got into college. The site now has over 30 million people registered. With lots of new communities, groups and alot more features to make passing on your message to your friends more meaningingful. New features like who have viewed your profile are soon to be started as well as blogs for members who like to share their writing skills or just some notes. Watch out coz lots of new features are going to be available to members. Have fun with the site.
PS - Lots of Indians (not only from mumbai) are registered to the site.
