Mynz-i is a peer to peer image file-sharing application that displays thumbnails when connected to other users using the program. It has some features that are similar to icq, one being you can select users from the main user list and add them to your personal list of preferred users, where they show up either in the online list or offline list upon program startup. Selecting a user from the main user or personal user list and then right clicking allows you to send them a private message providing the other user is not behind a firewall. Users behind firewalls can initiate and maintain private message sessions but cannot receive initial requests. In the public chat rooms all ( firewall and non-firewall ) users can communicate. Also firewall users can connect to other users to view their content.
