I would just note that making textures for existing clothing, making poses, making facial expressions, making characters -- these are all easier than making clothing. And the skills you would develop making textures, including making promo images and submitting to the RO marketplace, are things you would need to make clothes. So that may be a more sensible place for people to start.

Regarding facial expressions, there is a little new trickiness there in LF and Dawn because of the combination of morphs and face chips. When you save an expression you want to do it in a way that doesn't erase a character; that could maybe use a tutorial or something somewhere, or at least an explanation of best practices. (Even better would be functionality in Poser that makes it easy to separate character morphs from expressions.)
