These are two features that come with a premium MillionaireMatch membership. If you would like to recall a message, you can delete a message, photo, or an entire conversation you've had with someone. This helps if you made a mistake and sent something that could have been taken the wrong way. The feature also helps to protect your privacy and ensure that your name and profile will no longer be viewed by someone you don't trust. Of course, you can also block any profiles that make you feel uneasy, but the recall messages feature helps. If you would like to reverse your matches, that means that you want MillionaireMatch to only provide you with profiles that are similar to yours. While you may not see a lot of diversity in your match options, you might feel more comfortable matching with people with similar likes and dislikes in their profiles.
