Perhaps we need to distinguish accounts that are established purely for commercial purposes, and maybe we need to further distinguish actual *businesses* setting up accounts for advertising purposes vs. people who are just clearing out their garage. If theres a way to isolate those kinds of posts, like a board for business to post inventory and specials, that might be better, because then we can choose to view it or not. It doesnt have to come up on the recent posts list, and it doesnt have to be open to discussion, just a simple "Heres my store, this is what I have, call me if you want."
I tell ya, I'd rather have that that all these paper catalogs. I can only line the cat's litter box so much.
