As I said in the other post I have already set up a web site for this. And no it did not fill up quickly. In fact I was just about the only one who put up any photos.
I'll venture a few guesses at why the site didn't fly.
1. It wasn't promoted by the national clubs.
2. There was no clear payoff for contributors.
IMHO, a well-promoted website for Model A documentation would eventually fill up with quality photos. It's true that only a small percentage of users would submit content. Actually, that is true of every organization, club, association, or company. In every case, a small core group does all the work, and everybody else benefits. But you'll still get the occasional upload from guys doing restorations. Eventually every Model A part would be represented and available for reference and judging. And of course every photo would need to be vetted. But this has to start with MARC and MAFCA to be successful. This is one good way for them to solicit input from the Model A community.
I know I'm in over my head... I've only been in the hobby for two years, and only read the RG&JS twice, but I read every word of it, and it just occurred to me that it could use more photographs to illustrate paint and plating, and the various changes from month to month and year to year.
Just consider this "newbie" input from somebody interested in getting deeper into the hobby.

Didn't try to make waves...
