Ok.  Over the past few days I've run across a number of tutorials that have been posted with regard to working with line-art (cleaning, coloring, etc.)  Well, I've found a number of good ones and I must say that the ones that Getty ([link]) has posted are at the top of my list.  Great going!!!  

As I continue looking if I find other tutorials of note I'll post them here.  Also I've decided to start using my "Fav's" list.  I don't know why I haven't been doing that so far.  I've found a GREAT number of images that have been WOW!!!
