[Air-L] informed consent

I am curious as to people's experiences in gathering informed consent? Our university has a paper document that it requires participants to sign -- but I was wondering if any of you have any experience in alternate ways of gathering this consent (i.e.: email or electronic document, printing out and mailing back or even scanning in a signed copy of the document) and any problems you encountered. any help would be much appreciated. cheers erika ~~ Erika Pearson Dept. of Media, Film and Communication.
