That's possible, since the J2O listserver query program only queries Nimrod's listserver, and from what I understand, Contrabandent and his aren't syncing for whatever reason.

Sure, basicially, the old epic list server program (the server program that tells JJ2 what games are currently available to join) had some pretty big flaws, and I'm essentially creating my own list server program. It has it's own flaws, but they aren't nearly as big (I think...some will argue about this). It adds much more functionality for the server admin.

That should do it, but the JJ2 binary has listservers hardcoded into the .EXE which it tries before the ones in the registry, but that shouldn't be a problem, since they're all extinct and JJ2 looks in the registry after it notices all those are dead. However, your JJ2 binary might be hacked (I know they're out there) to use Contraband's list server, and then possibly others. You might have downloaded a modified binary and not realized it. Open up the JJ2 spy window (search the forums to find out how, I can't remember the instructions off the top of my head), and when you create a game, it'll tell you what list server it's using.
