We use Visual Source Safe, I have no experience with the
other software you mentioned.
Whatever software you use, make sure you take a very
disciplined approach and run some test before working with the real
thing.
I'd recommend setting up a dummy project and working with the
other authors experimenting with the procedures that work best for
your working practices. Put together some rules and dos and don'ts.
We have one main project controller who can update the index, add
or delete files from the project, add conditional tags and all
those features which update the core project files. Other authors
can work with a copy of the latest project and check out and then
update topics, adding topic content and images. Having one
controller makes life a lot easier if things go wrong.
Yes, VSS is pretty unfriendly, and there is an overhead
keeping control of the RH files using the software. But it works
for us and helps me sleep better at night knowing I can back track
if things go wrong..
Kind Regards
