You are pointing your miner to port 3046 which is the specific config for Hirocoin. I pointed my miner to port 5550 which should automatically mine the most profitable coin for X11 protocol.
Anyway I can't see my address on the workers page neither. Maybe because in the last hour I found only 3 shares that are above difficulty 1. Anyway i'm stopping mining there until this issue will be fixed.

BTW the example config from the http://harmonycoinpool.com/getting_started# page is misleading because the port 3046 will mine only Hirocoin and the algorithm is set to X13 which isn't supported by this pool at all)
