of course you are not satisfied with this LimeWire. I stopped loading from this a time ago... it eats memory and it is slow and you don't ge4t any files anyway... If you get some files.. most of them ends up "cannot move to library" and you don't have the files anyway.
I think this stinks too. I have also tried to write and report this problem.. The email - help@limewire.com address (or what it was).. doesn't work anyway.

But i heard it will come an update soon... Hope that the new update will work anyway.
As far as i know this limewire-**** is the only thing for macs... For pc:s there are many different kind of workign networks.. (WinMX, Gnucuelus ??, Kazaa and so on)....

Of course - there might be some underground networks but i think many of them are very strange and hard to find out what to do and also to find them...
