Online Document Updates via Internet

[RobinGmail <robin.saunders@xxxxxxxxx>]

Hi all,

I have a problem that is probably common to a lot of companies producing 
documentation like Functional and Design Specifications were there is a 
requirement to have a number of people review and make comments. In the 
old days (I'm 40+) the reviewers were generally in the same building and 
we would just send the printed document for review and have it returned 
with lots of red ink and post-it notes. Nowadays the reviewers are 
global and usually review a Word document with tracked changes and then 
the poor author has to pull all these different documents back into 1 
version. It definitely takes longer than the old days and we have more 
iterations of reviewing than i think necessary.

So I'm trying to find an Internet based solution for allowing only 
invited people to get access and update with tracked changes and only 
have 1 copy of the document. Would Wiki provide an answer to my trouble 
or is there a better way?

Many thanks in advance and hope everyone is having a good weekend if 
it's your weekend now in your country.

Regards
Robin
