OK! Here's my two cents (everyone waiting to see what angry crap Doran is about to say...) But seriously, I have purchased some humanoid characters That I intended to use in animations. I am dependant on IKs and some of the items in question had no IK chains. Because of the importance of such a thing, I think that the lack of IKs should be a point the Vender is obligated to mention in there sales pitch. If I had known that there were no IKs for the figure I wouldn't have bought them, period.

It's like the free stuff section and thumbnail previews. If someone offers an item but provides no thumbnail preview I always say to myself "man, if this guy can't make a thumbnail image then why should I trust them to make a good texture, model, etc". the same goes for IKs, well at least for me. If they can't create IKs then how good can their work be. Since IKs are an important feature for poser items then the lack there of should be mentioned. In my opinion, to not do so is either lazy or misleading. Well, that’s it.

Oh, and I agree with the rest of the posts here, as well. A little common sense would be nice.
