Morphworld (3.0, in this case) is the site of one of the most prolific and greatest creators in poserdom: Traveler. Having been using his morphs since I found them (early into Morphworld 2.0). I'll tell you that they will work with V1/2 and M1/2. They all have to be applied the old fashioned way, but they are really incredible and I believe they influenced some of the morphs for the V3 figure, lol. There are also a lot of tutorials that are basic reading there -- good stuff. Lastly, you should sign up for the props club there. The stuff you get there is worth easily 10 times what you pay in subscription fees. Every monday something new, and a lot of the stuff finds it's way into a certain big store after it's been there for a short time. He's also still got some great stuff here -- including some that came as part of the props club originally. In general, though, you got the straight stuff -- unless it says it's for V3 or M3 then odds are it's for V1/2.
