So here we are in 2017 and I noticed that the wiki has not had an edit for around 3 years, but I still have had to bring it down every few months for security fixes.
So the time has come to kill the Whale – all the wiki content is now moved to articles on the CMS or deleted or published elsewhere and mediawiki has gone to feed the fishes.
It was a great collaborative tool in 2004 but I can do everything in a google doc these days and someone else is keeping that secure and patched (I hope!) .
It did make me realise how much content had no links in or out and thus was effectively invisible.
There is still a private wiki to wrestle with and vSprawl is presently wiki based. But this is at least a start in simplifying the estate a little.
