Mahara is an open source e-portfolio tool, which I am about to start evaluating. I haven’t really had a lot of time to look at it yet, but here’s their demonstration video.

I’d be interested to hear any feedback. If you want to play with Mahara, it’s been installed on the Learning Lab server The address is http://learninglab.lincoln.ac.uk/mahara/ (but you’ll need an account so drop a line to either myself or Joss Winn in CERD, and we’ll set you up.)
