I don't really know what the difference is ... I thought you came up with those rules. In reality, though, no individual is profiting off a slide show thrown by a non-profit. With outfitters, gear shops, etc., most of those shows are acutally promotional events for some company. The clubs typically aren't running these events as huge money makers. I think the distinciton still makes sense and the clubs (and Lowell) should be posting slide shows here for the community.
