Greetings!
At the moment I use
xmule as an edonkey client and I must say I'm very impressed. It works (and looks) just like my beloved emule and the best thing is you can continue the temporary files you were downloading under Windows.
I have yet to find a good replacement for Kazaa. I took a close look at gift, however word has it that they stopped development as the fasttrack guys kept changing the protocol to keep out foreign clients. If you find a good one, please post it here, I'd like to know about it as well!
Good bye!
