I don't know if it "remembers" hosts, but try these:

connect1.bearshare.net
connect2.bearshare.net
connect3.bearshare.net
router.limewire.com
connect1.gnutellanet.com
connect2.gnutellanet.com
connect3.gnutellanet.com
connect4.gnutellanet.com
gnutella.hostscache.com
gnet2.ath.cx:6346

Copy-and-paste the above IPs into Mactella's New Connection field and click Add.
