I have no friends on my friends list and have no way to add friends... can anyone help?

When you are viewing the profile of someone to
whom you wish to send a 'friend' invitation,
the far right orange button 'Add as friend'
beneath their picture, is what you click on
to send the invite.

It will give you an option to add a message.
It is up to them to accept to have them appear
on your 'Friend's List'
~~~
If, after you get a Friend, and they do not
appear on your profile, you would go here
to have your Friends and/or Testimonials show:

Right hand column, last 2 options.
