How to Contribute to Documentation?

[Brady, Mike]

There is a lot of wisdom gathering on this mail list that I think would 
be more accessible if it were in documentation somewhere.  There have 
also been specific corrections to the the existing documentation raised 
that have never been applied.

There are currently three sets of documentation (four if you count this 
list) that I am aware of.

[1] The Wiki (http://wiki.kolab.org) which, as others have noted, seems 
to be defunct.

And two sets of manuals that have different formats and content at

[2] http://docs.kolab.org/
[3] http://docs.kolab.org/en-US/

[2] is linked to on the kolab.org home page and seems to me to be more 
complete, but [3] is often what is returned in Google searches.

 From the project what is the "official" status of each of these sets of 
documentation and which/how do we as users contribute to them?

Regards

Mike
