It would be nice to have a "separate" Stencil Files section. For members that would like to contribute those types of files to the collection. Right now, they're lumped into the side-art section. Also, to make the site more comprehensive, perhaps a section for cabinet specs like Jacobud's, and a section for color codes.
But alas, it is an Artwork site, so offering all the above might change it into more of a total restoration, one-stop shop site. Which might not go well with the intent of the site.
