Thanks Voltaire for the heads up ;)
"This new version of WinMX is based on a completely new architecture which has not been widely tested. There are many new features, and many new places for things to go wrong. Because of this, we anticipate there may be minor or perhaps major issues with the software, and we may be releasing newer revisions for beta testing on an hourly basis. As with all our software, you use it at your own risk. If you are uncomfortable with this, please be patient and wait a few days for us to finish testing and release a final version 3.0 to the public."
WinMX is a FREE file-sharing program like no other. It allows you to simultaneously connect through the decentralized WinMX Peer Networking Protocol and to many networks based on the OpenNap and Napster protocols. This means more users and more search results than other sharing programs. WinMX also supports any file type, allowing you access to a diverse assortment of shared video and picture files as well as the usual MP3 Audio files.
