you know Kazaa Lite offers you no protection against hackers or virus' right?
it also rewrites some of your registery to allow some more direct contact.
even standard Unregistered Kazaa is better than that.
i like the 2.5.x search engine, allows upto 40 searches for the same name over 4 different networks
can connect to eMule servers
can connect to website directly
you can have upto 200 callback names per search (thats not upto 200 instances)
unlimited uploads (but thats really pointless and i turn it off)
unlimited downloads (again pretty pointless and i tend to set it to 5max)
configureable pipeline speeds
peer2peer points manager (allows you to have free purchaseable downloads (gold ticker) when you download enough yellow ticket downloads)
peer2peer Extentions (the new more stable and safer p2p networking)
better search facilities (upto 100search tabs)
better family filters (they actually work now)
known virus, pirate, porn files are now truncated
generally is far better and easier for sharing files, especially with the new PerUser settings - so you can now allow only certain people to access your shared or a specific share folder.
