Art Fire has also added a Market Hub for their sellers. It is already set up with sties, you just have to input your addresses. (click to enlarge)
It appears on each listing page in the lower right corner as seen here:
Crobbies has made a few changes since my last write up as well. I had inquired about a shop policy area...I was not sure if I was just missing something. Well, the next day they had added a section for shop policies. The response they have had to suggestions has been quick and so far, no problems with the additions. I also saw on Twitter that once their no fee special ends on Valentine's Day, the new fees will likely be zero for listing and 3% for sales.
