today was the first roll out of what i am sure many updates in 2010 for Yahoo stores and Yahoo Merchant solutions. If you are not aware  of what they released check out the yahoo store blog @ http://www.ystoreblog.com/blog/2010/01/january-2010-release-notes/

One nice thing they talk about is “bringing you customer registration features in 2010 has been one of our top development priorities over the last several months” now that is something that i look forward to as a yahoo MS customer and Developer!!
