Our Review: Its Gnutella for the Mac, and unsurprisingly it's called Mactella :) The whole idea behind this is free file sharing for the entire world, and having software that everyone can use at no cost. The reality is that people use it to swap mp3's, games, apps and lots of other things that generally breach copyright laws... ah well... Anyway, Mactella is a good file sharing program, and offers no more or no less than any other version of Gnutella. It also has firewall support, but it didn't work over our NT4 network...
