This 'Thing' is another good one that until now I have been completely unaware of.
How many times have I ended up with different versions of the same document after sending out for review, wondering which one was correct? - Too many!
And all along there has been a solution to this dilemma hiding from me with the ability to track changes in a document from many sources.
I will definitely be making use of this in the future, especially as I have two academic supervisors and an industrial supervisor to make comments on my work; each of whom will no doubt have differing opinions.
