That's the problem right there. You're using your own XMPP account. So you'll only be able to see people who are using the xmpp.jp server, which as far as I know is no one.
Remove that and just enter 'Dr. Saturn' in the XMPP account name field, and the same password you use for the forums. It will automatically change it to use the Titan XMPP server, which is where most people who use Paragon Chat hang out.
