Think this is the right forum thread...
It's a site where you can lend support for ideas for a book before people start writing, and if it gets enough support then it gets written. Haven't explored properly yet but might be relevant to some.
The link I put goes straight to the first part of Python's Terry Jones' new story, so worth a look even if no interest in the supporting/writing bit.
Apologies if it's shit, I don't work for them just thought it might be interesting or useful to someone!
