i use limewire. i couldn't find kaazalite when i went to the website... they wanted me to pay. i guess you have to go around to download.com and do all this other stuff.
i am using limewire. i use it at home and then use it at school as well during open labs cuz they have T1s and i have a 56k... blah... jen's in the stone age.
my friend uses kaaza tho... he managed to find a computer program that is normally priced at $900 a pop for free. I haven't heard him complain about it yet.
