Accessibility Camp was started after just one tweet back in late February 2009.
We started with Accessibility Camp DC five and half years ago and have had many other Accessibility Camp's around the world.
If you're thinking of running an accessibility here is a blog John F Croston III wrote about " Notes for Running an Accessibility Camp ", along with Microsoft Word version of "Notes for Running an Accessibility Camp" or PDF version on "Notes for Running an Accessibility Camp" .
