Once you have found a profile you are interested in, there are several ways with which you can interact with that individual.
You can send that member a message via the send message button or window, leave a comment on any profile or picture, show interest in another member or use the 'Chat' feature to start a live chat session with that member.
Once you register, you will be able to add friends, add favorites, send personal messages and use the live chat feature to interact with other members completely free.
You can also leave comments on member's pictures and profiles.
