I think it is an excellent idea. Of course it would mean more work for the web guy(s). But I don't think it necessarily would need to be in a Members Only section, not like a members phone directory (if we had one). On our main page there is a link: Props and Mods, I can't see why something like that couldn't be added to that page.... other than the work the web guy(s) would have to put in.
As far as the concern regarding locations to buy things, locations like Wal-Mart or the like are fine. It is unauthorized dealers whom we can't mention specifically on an open forum. Mentioning that you found a great deal in Wal-Mart's fabric section, for example, for the neckseal project is perfectly fine.
Who knows, maybe I when I tinker around making my DLT-20a, I'll do some sort of tutorial as well.
