Charlie, the "private" videos would be for every one who participates according to the guidelines of being committed to the challenge. It's not just for full members.
Sharing with the community is what it's all about and that includes not only what you can get from the forum but what you put into it as well.
If these videos that Robby makes, which cost money to make, were open to every one, even those who are not participating, it would defeat the purpose of getting forum commitment.
Any one, including those who are just looking, would then reap the same benefit of those who do the time and commit and that would not be fair.
I don't consider asking being rude, but you should know that this forum is all about sharing and a steady commitment to be here and getting involved in the whole community.
As I have grown older, I've learned that pleasing everyone is impossible, but pissing everyone off is a piece of cake.
