Go to your profile and send either your username or email to me.
Wait for me to add you as a friend. You should receive an email, follow the directions in the email and accept the invitation.
You're all set you can watch movies through the web player at plex.tv or use your Xbox, Smart TV, etc. (iOS requires a one time $5 payment). Feel free to make requests for new content through Vcast Requests, you can sign in using your plex username.
