Hello,

I think it's cool that NB allows us to communicate with our classmates about the readings, but I also like how I can make notes to myself as I read.

Would it be possible to put the lecture notes up on NB so we could annotate those as well? I'm thinking for personal use, but it's also possible that someone may have a question for the class (e.g. about a formula) that they could make a note of.  

At the very least, does anyone have any software suggestions for managing and commenting on PDF's (short of buying Acrobat)? 

Thanks,

Steven
