I have been trying to contact a porn star to see if she provides.  I tried emailing her but never got a response.  It was suggested to me to PM her that she was good at getting back to people that way.  However where can I find the link to PM her?  I was on her profile but the only links are the people who reviewed her.  Am I missing something?

when they post, and then only if they are not using an alias.

If she is not answering her email, I don't know why she would bother to answer a PM.

You can only PM her if she has a TER handle and has VIP status on TER.  You can try doing a search for her on the Porn Star board or on other relevant boards to see if she has posted or been discussed.
