Think of a discussion board, then cross it with that corkboard in the hall outside the administrative offices in your high school, and imagine what a programmer might do with it. Then check out webnote. Does it look anything like what you were imagining? Be sure to try the filtering feature. This is cool cool stuff. I’m going to try and get this up and running on my server once the code has evolved a bit, it’s still under very active development. Note that you can jump to the root address (www.aypwip.org/webnote) to make your own ‘corkboard’ and read about the codebase and the developer’s plans for it.
This requires a modern browser, Firefox, IE 6 or Safari, just fyi.
