Orkut is unique, because it's an organically growing network of trusted
friends. That way we won't grow too large, too quickly and everyone will
have at least one person to vouch for them.
If you know someone who is a member of orkut, that person can invite you
to join as well. If you don't know an orkut member, wait a bit and most
likely you soon will.
We look forward to having you as part of the orkut community.
