Okay, I've created two pages.
RaspberryPiBoard is the starting point for advanced users
RaspberryPiBoardBeginners is the starting point for beginning users
I've also created a new category: http://elinux.org/Category:RaspberryPi
If anyone creates a new RaspberryPi related wiki page, please include the following at the top of the page:
[[Category: Development Boards]]
Obviously a lot of the content on there right now is educated guess work on my part, plus nuggets of info copied and pasted from the forums. The whole point of a wiki is that the community as a whole (no one person or organisation) owns it and updates it as time goes on so everyone should feel free to correct mistakes and add knowledge as they go.
Clearly in the early days, it is first going to be the Raspberry Pi developers and then key third-party developers with access to Alpha boards that are going to have the most to contribute.
