Hi folks, First, thanks so much for supporting AAC! Anyhow, i've been pondering with the idea of turning the site into a 'semi-wiki'. If you are unsure of what a wiki is, take a look at wikipedia.org. The basic idea of it is to let anyone freely add or edit the content of a web page. Right now, I feel that with AAC/Lessons in Electric Circuits, there is no easy way for someone to add content to a topic, or to fix an error. I know there are people willing to do this, but there is just no easy way for them to do so. My idea is to add an 'Edit' feature to each page, so a visitor would be able to add content or fix any errors they have spotted. When compared to a wiki however, the difference is that these changes would not be instant. Instead, I think it would be best to have any changes approved by a group of editors. I think that the approval is neccessary in order to keep the book consistent, and also weed out any inappropriate changes. I would love to hear any feedback (positive and negative) on this idea!
