How to help lady get on p411?

A lady asked me to send her an invite to join p411. I don't see anywhere to do that on that website.Anybody know how?

OR...

Does a lady first apply and then get vouched for by a client? If so how does a lady apply for membership and then how does the client provide the vouch?

I have been on p411 for years and have 44 okays.

1. Add her as a non P411 companion.
2. Invite her to view your profile.
3. After she views your profile, you will be asked if you'd like to vouch for her.
