Shareaza has features that are unheard of in other file-sharing applications, from ghost ratings to a completely user-configurable queue area to multinetwork support. Shareaza started out as a Gnutella client but recently branched out and developed Gnutella2, a completely open and documented network. Boasting 50,000 users, Gnutella2 is well on its way to the top. In addition, Shareaza supports the eDonkey network and BT. Shareaza's interface is easy-to-use yet powerful and fully skinnable.
Shareaza's download core was purpose-built to provide optimum performance from any number of sources. Shareaza can manage your download queue automatically, or you can take charge and modify the status of files or even individual physical transfers and sources.
