I have learned from this thread "Track changes" in LaTeX that there do exists some change tracking mechanisms.
What I need now is more than change tracking but also change accepting similar to that in word.

There is a button in word that you can accept all changes and then the change tracking record will all gone from the doc only leaving the final draft. This is different from only showing the final draft.
I actually want to delete all tracking record at some point to progress to next version. So that you can start change tracking again and only show those "new" changes.
I know there are version control systems, but majority of my collages do not like them.
Is there any possible solution?
I feel if some pre-compile user-command can be supported this is possible. Here is what I mean: How to let latex only run one user defined command and save the ouput to a tax file
gitandsvn. With those tools you can view changes, merge them together, reject them, restore previous version and work with other people. You can also collaborate with people through websites like GitHub. – Henri Menke Apr 09 '14 at 17:54\track{<some text>}..? (Admittedly, I haven't used track changes since about 2002 so I don't know how it works.) And, besides the fact that there are many examples on the web of how to twistsedinto non-greedy matching, how non-greedy do you need it to be? In fact, withxparse, you could make each argument be delimited with a different delimiter, which would make things easier to parse... – jon Apr 09 '14 at 17:56
