Well....there's one I can think of....who is often overlooked.....probably always overlooked when 'skinners' are brought up as people of 'note'...and that's Frogboy.
It's almost always forgotten that he ain't just the CEO of Stardock but is actually a skinner....just like the rest of us...except his 'vision' of what makes our skinning community is - what makes our skinning community.
Without his singular enthusiasm what we all know/perceive as 'skinning' would be a whole lot different.
All the names there that you listed, bar none, also make skinning what it is....from APB to Zubaz and everyone in between....
Darn...from Adni18 to....
....oh, if I think harder I'll bet I find further ends of the alphabet....
