CommFort is a multi-functional client-server LAN/Internet communicator combining an advanced text chat, voice chat and file/folder exchange system. It is adored for its thought-through text chat, which besides the common "smilies" offers convenient image pasting to dialogs. The low-latency voice chat gives the feeling of talking to a person standing next to you rather than sitting a globe away. And sending a file or an entire folder is just a matter of a mouse click; the automatic block size adjustment allows reaching the highest speeds possible when exchanging files over networks with 32 kbps through 1 Gbps of bandwidth. The program takes care of incomplete file downloads, automatically picking up broken file transfers and resuming them when the network is available. With the new version of the software, peers can chat and exchange files even if a party is behind a NAT service. The latest edition features improved user authentication and flexible administration functionality. Users can now be configured individually. Clients can now manage users from their client windows to as far as hiding selected users' IP addresses, managing channels and restrictions. Windows users with restricted permissions can also enjoy the program's functionality in full. Chatters without the client application can connect to the chat using terminal clients. Corporate users can have the program log all communication on the server side. The very look of the program is completely new. It's completely skin-based, and the improved skin format allows putting any appearance on main windows of the application. CommFort utilizes improved network/CPU load balancing algorithms and thus can handle thousands of simultaneous users and chat sessions while keeping server and network load low.
