I have seen better than that thread on the forum somewhere but as I remember it also didn't give all the ins & outs. But it does give a lot more info. A search of the forum is the way to go.

I did a quick search using skin* & came up with some discussions but no definite directions. You might want to send a pm/email to IamAboveTheLaw76 b/c they seem to know how to do it. I don't know how helpful they'll be. You could also try deepblue & he is a regular member on the forum.

Here's some results: Post A, & post B, post C, post D, post E, post F & post G. If you want to search thru the remainder of my search results see HERE!
