No there aren't any working 3rd party pools. http://syncoin.hashrapid.com is the only (after the official crap) which can give some shares, but you'll never find any blocks.

Im testing the official pool,  http://synthase.violates.us:33550 now and it does give shares but I don't know where they go or where to find my personal stats. Dev could be doing anything with them. I even tried to solo mine @ wallet with my laptop and yes i managed to get a devastating 3 khash/s without any income of course.

E: Wait, what the heck?! Link http://syncoin.hashrapid.com actually leads to some Grumpycoin pool?
