The first post in this thread is dated a year ago. Steven hadn't started working on v3 at that point, so these skins were designed with 2.5 in mind. They should work. In my experience, skins designed for 2.5 will work in 3.0, but 3.0 skins will not work in 2.5 as Steven as added many new elements for v3. Your mileage may vary.
