The way LaTex works is that it takes underlying source code (which is plain text with a bunch of extra syntax in it) and compiles it into a great looking PDF.  I could send you the underlying source text as a MS Word file which you could use when you respond with corrections, edits and/or rewrites (using "track changes," if that is what you prefer).  If you ignore the odd syntax mixed in with the text, it is easy to follow.  However, I would appreciate it if you read the PDF when actually doing the editing, so you can see how the article will actually look. 

Let me know if you are willing to give that a try, and if so, the best way to get the PDF to you.  The MS Word document I can just upload via the website.  If not, no worries.

Thanks,
Spiro
