Just a note: discovered that the pool confirmations were set at 60 blocks but the current wallet confirms blocks at 180 confirmations. So I decided to update it. The new setting sort of confused MPOS and it will take some time to clear up -- do not be surprised if large payout suddenly "does not work". It will.
EDIT: the pool has already passed 1 Ghash/s, wow! Do not worry, the server is barely noticing the load.
Yeah, I figured that's what happened when I saw a good part of my confirmed balance go unconfirmed.

The web interface is working perfectly now. Everything's refreshing correctly, the dashboard is streaming, and the three little beeps with each new block found are even coming through loud and clear!
Currently about 2/3 the network hashrate though - so if there's any 51% attack, just remember, we know where you live.
