I'm not likely to create one myself, but just wanted to say I'd be happy to help out with other people's.
My skills which may be useful are:
1) Checking spelling, grammar etc.
2) Drawing icons, tiles etc - if I knew what size it had to be, and what format, I could produce graphics.
I don't know how easy it is to involve a second person, or whether it's easier just to do it yourself, but thought I'd make the offer anyway!
Anyone else who could help out could add themselves to this thread.
