First thing I will recommend is to not use your email (if it even is yours) as you nick in any forum.
Now, as to getting another P2P application, yes, I think that getting another one is a good idea (I've got 3, if you count BitTorrent). The reason is that different things are more available in different networks. For example, LW is better for music.
One, oh so popular, P2P application is BitTorrent (@ www.bitconjurer.com for the official one). It is kind of different than other "conventional" p2p apps though as you have to look for the files you want to dld yourself in the net: it doesn't have a search function.
I also use Phex (http://phex.kouk.de/). It is also a very good application. Some people will also recomend Acquisition (http://www.acquisitionx.com/), but I've never tried it so I can't tell.
