I read somewhere they were banning squares. Dunno why but I hope it doesn't extend to circles and triangles -- I really like triangles ;-) Of course, that might only be in the Marketplace, not the galleries. And maybe only in the first preview pic/thumbnail, the rest might permit judicious use of artistic squares, especially in texture sets. But you'd probably best be careful all the same. (Note to lurkers: Yes, we are just clowning around with this. No, we don't mean any harm. So there's need for anyone to get all huffy or bent outta shape. :-)
