Have you ever got an e-mail from a student asking you to comment on a draft of a survey? How do you do this efficiently? I find it strange that most online survey tools that I have seen and used do not provide a specific function for it! Anyway, at least I found a tool now that can help and avoid creating a PDF or even printing the survey draft for manual annotation. Have a look here.
To transfer big data files to colleagues and students can be difficult. Wetransfer seems to work properly.
