Personally I use both LW & Phex. I find I can often connect to a broader range of the gnutella network with Phex because it connects to many more of the 'other' gnutella client programs whereas LW mostly only connects to other LW users. Thus, if seeking rare or difficult to find material I will often revert to Phex.

Bittorrent is another option. I keep all these options alive. But I do not use LW for torrents. I use Vuse.

When I use LW I try to browse host with similar material as I am seeking. Sometimes that in itself can lead to material I am seeking or help in later searches by connecting across a different spectrum of ultrapeers.

Dear Lord of the Rings:
Thanks for your info but I finally took the decision to throw Limewire to the trash can because it is a useless network in which its computers are the laziest of all the computers in this planet which have decided not to work anymore and everything ends waiting for sources (ETERNALLY).
I am really very sad about it but there is no choice.In this network you can download only Madonna(if you are lucky enough)...AND NOTHING ELSE!!!!!!!!!!
I will try with Phex and see what happens...perhaps we will meet also there in the forum.
Bye and best regards
