If you want to increase your chances of getting messages, the #1 thing you can do is to upload at least one picture if not many pictures so that people can who they are talking to. It really goes a long way for people to be able to put a face to the person. It also helps to write something interesting about yourself on your profile for people to read when they view it. Being online a lot also makes it easy for other users to find your profile and of course, it never hurts to send a few messages to other LuvFree users and see if you can start a conversation that way.
