Russ Shafer-Landau has the 2010 Workshop announcement up. Here is Russ's note:

Dear Colleague,
I’m pleased to announce a call for abstracts for the Seventh Annual Metaethics Workshop, to be held at the University of Wisconsin, Madison, on September 24-26, 2010. Stephen Darwall (Yale) will be this year's keynote speaker. Abstracts (of 2-3 double-spaced pages) of papers in any area of metaethics are due by May 1. There is a limit of one submission per person. Speakers in the 2008 or 2009 workshop are not eligible to submit abstracts for this year’s event. A program committee will evaluate submissions and make decisions by early June.

Questions may be sent to Russ, whose contact information is on his website.
