Thanks to both of you for the advice.  Is there a way to create the "question and answer" experience that Link has in either of these?  I use Hightail for secure email upload/download of files (especially large files) but the clients that use Link don't want to use that kind of a service.  They want to be able to answer the template of questions I have designed inside link in lieu or a organizer type document that I would upload to them.
