You seem to miss out the point completely. The forum is not just a chatroom where you come and discuss things. To many people it is an online reference, if not THE online reference about a vast array of rare prototypes and unbuilt projects. An interactive, ever-changing and expanding database. Sometimes you get a reply to a post months after you posted, because someone has just discovered the topic you wrote in. Sometimes you come across a thread that was started three years ago and add to it if there is new information. Sometimes a new member revives an old thread and adds an anecdote, a detail, a comment. A forum has a life of its own!
Also, you seem to think I refuse to give sources. I do not. An almost complete listing of McDonnell model numbers was recently provided by a fellow member in the designations section. This sheds new light on quite a few projects. As the moderator of the Designations section, I feel it's my duty to extend that information to other parts of the forum in the best way I can.
