I was just wondering the same thing.

The pool shares the daemon with the giveaway daemon, but even though I requested an address for "nomp" using getaccountaddress, the SLM seem to be going into the "" account instead. Hmm might be a bug with the client, will look into fixing this.

I've temporarily transferred funds from the "" account to "nomp", but it seems like the past few payouts were lost cos I don't seem to have captured any errors. The current immature blocks should be paid out once they mature.
