@ossobuco,
I'm mildly confused by the lack of questions in this thread. You're not really providing much in terms of context to this discussion.
Are you trying to make some kind of point regarding new members asking about art authentication and/or appraisals? I'm pretty sure our membership doesn't contain any professional auctioneers, art appraisers, museum curators, etc.... And if we do have a few of those former professionals, they shouldn't have to give their advice for free.
Most of these art related questions could and should be taken to professionals for proper appraisal. And I expect that these people are too cheap to do so, and worse, are likely not even to have anything legitimate in their possession in the first place.
