Wow, I just downloaded Gnotella and could not connect... read all the FAQ stuff... no help. Read the post about adding public.bearshare.net and I did and it immediately connected...

What is wrong with:
connect1.gnutella.net
connect2.gnutella.net
connect3.gnutella.net
connect4.gnutella.net
gnutella.hostcache.com
router.limeware.com
gnutella.hosts.com:6346

None of them work!
