Friend groups have been on orkut for some time now, but we're now making them more accessible throughout the site to make it easier for you to create new groups or add new friends to them. Here's what's changed: when you add a new friend or accept a friend request, you can now select which group(s) you want to add them to. You can also modify these groups (rename them, remove them or add new ones) either when you add or accept a friend, or on the friend management page. And we've turned friendship levels into groups for you, so that you can send messages to all your best friends, or see all the friends on orkut that you haven't met offline yet.
If you're not sure what groups to create, we've made a few default groups to get you started. This will make it easier to categorize your friends. You can always change the name of these groups if they don't suit your particular need.
We're also planning on a bunch of new features so you can use your groups to make the orkut experience more tuned to your needs. Stay tuned!
