heyas; it would be tons easier (read: more people would do it) if there were a checkbox type deal instead of an icon to be placed on thumbnails. we could institute the markers for 'requires commercial item,' 'requires other free item(s),' and hey, how about my favorites, 'for non-commercial use only' and/or 'free for commercial use.' i have icons i use for the latter, and it's a pain to remember and to stick them on every thumbnail. then i started putting the $ in the corner of the description of my stuff that requires commercial items, and that is so much easier.
