Ok, true enough.
But the wiki was user-run. Why not release the information back to the user base and allow those capable and willing to rebuild in a better structure; instead of a wiki, why not link to a hosted Web page? Cost incurred for hosting would be minimal (paid hosting vs "free" ad-driven hosting) and anyone that would want the info available again could donate per annum until a sustainment solution is met. For the numbers-oriented, WordPress hosting plans are $99-$299 a year; GoDaddy is $72 a year for one of their packages. List is noninclusive.
On the Wiki subject, and I'm not being critical here, but aren't all changes on a Wiki subject to community or administrator approval, so someone can't just arbitrarily just change something and then post it? Never created or modified a Wiki before but I really use them. The encyclopedic layout of information is in a better format for, say, mobile users that are wanting to do some reading while out and about before doing some flying. Again, not being critical but I don't understand how users were able to mangle up the Wiki so badly, it has to be taken down. I'm only curious because if this is done again, mitigating measures need to be taken. It was very beneficial to me and other new players can greatly benefit from it too.
So, just my two cents on it.
