Five days ago I published a fairly scathing attack on the folks that built ExcelMashup.com due to their poor support for folks that wanted to provide feedback. Well, credit where credit is due, they have been pretty quick to respond as I have been informed that the site has been updated with a link to the dedicated forum which is hosted on Microsoft Answers. In an offline email exchange I promised them that if they did the right thing then I would update my blog accordingly, hence the post that you are reading right now.
Note that I do not know whether or not they have started responding to the email alias mentioned at http://www.excelmashup.com/Content/Community.html.
