Boo effin' hoo
Using Word every day to write documents, and having to provide amended documentation to clients in track changes, I can say that Word works very well indeed.
If Mr. I-write-on-a-mac-cos-i'm-all-creative doesn't bother to familiarise himself with *the single tool of his trade*, then he deserves all that's coming to him. Good luck with the 'buggy' track changes in Libre Office. I'll stick with properly understanding the perfectly good tracking in Word.
