PDFCROWD!! Super cool!
This is a super cool site I came across during an Elluminate session on the E-Moderation course I'm doing with The Consultants-E. Gavin told us about it and I just checked it out :-) I love it. Just off the top of my head, I think it could be very useful for building up my own e-portfolio. In the classroom, maybe to work off line using it as an authentic text for a text-based presentation, discussion, language focus? I don't know, I still have to think more about it.
