Using the same software as used by Wikipedia, we have customised the configuration so that you use the same username and password as you use for everything else on the server. We have created a basic framework for a "company manual" with all the pages we think you might need to centralise what you do to make it easier for your staff to find things, and to help get new staff up to speed quicker. MediaWiki is easy to learn, and even easier to use, and keeps a history of changes which is particularly useful if you are pursuing (or seaking to retain) an ISO9000 type accreditation. - This feature is part of the Base Install Module and was added to all our systems on 28th February 2009.
