gcolyer - i'm completely immature! nothing personal, and don't worry about it, I certainly don't!
However, do go to the flyer forum, it has a similar sized audience and a forum specifically for your needs.
I also think there is a difference between advertising a group share and an aeroplane as a complete unit. I can't think of a decent analogy, but the concept of one being an advert for a membership in a club that promotes grass roots aviation and other being a commercial "thing" seems to be pretty spot on .
