I'd be willing to bet I have enough notebooks to fill a 10 gallon tote these days. Everything from 7th Sea adventures when I was 13 to complete Deadlands campaigns that will probably never see the light of day again.
I know I don't have the time, patience, or money these days to keep up with a website. On that note, what would the chances be for CGL to host a fansite for users to post unofficial material to? I know if I had somewhere to put it where it wouldn't disappear in a week, I'd love to share my 2073 Knight Errant Armaments weapons log pdf with people.
The only issue I foresee with going this route is that most people won't like it if there is the standard RPG company "blah blah blah, all submissions give us copyright, blah blah blah" tag. I understand the general need for such things for the cases of pitches as the company may already be working on something similar, but I would think that it would be detrimental in this case.
