Please do a review of your addons categories please. With the v4 Curse Client being released, categories are getting more imporant. Please take a few minutes to go over the addons that you have and verify the categories are correct.
Somehow in my new project http://www.wowace.com/addons/epgpreserves/ the category "achievements" is always visible on the project page; it is, however, not selected when I edit the project.
My addon should only have the "guild" category tag.
