Before I can spend any more time browsing vendor offerings at this site I need to get the option to exclude any given vendor from my view. This exclusion list should be a part of my profile and I should be able to place a vendor on that list by right clicking on the vendor's name and marking it excluded (there might be other useful options available with such a right click.)
There are vendors that are creating very special purpose parts and their list of parts goes on for pages when browsing certain categories. There are also vendors who produce things of absolutely no interest to me and vendors who offer just plain junk. Until I have the ability to filter them out of my browsing results I will be absent and spending no money on any vendor. When I get one of the regular Shapeways emails saying that this feature has been implemented I'll be back.
