I am very new to LaTeX, only did a few documents but now I need to set up a workspace for two people working on a project. The project will be about 300 A4 pages. At the moment we are working with TeXstudio 2.2.
Our set up at the moment is that every time someone works on an part of the project, he creates an new *.tex file and writes in there, starting with a "\section{}" and saves with filename_v1.tex in synchronized folder (drop box). The other one checks the document afterwards and saves it as filename_v2.tex, filename_v1.tex goes into an archive folder.
The problem now is that we have many *.tex files and if someone updates a file to a new version, the other one does not see what has been edited (for example if someone knows: MS Word has a function to highlight edits and show what was edited).
So if someone has tips how to set up a good work flow for two people working on a project please let me know. It is getting more and more crowded every day.

Thanks a lot for help!
