It's probably not even in the consciousness of anyone on the forums, but the Unify wiki still exists, and still comes up on Google for some queries. And it is absolutely, utterly worthless in 2019. Actually, code sample for obsolete tools are worse than useless, as they're likely to frustrate any new users that come across them. There seems to be a single user active within the last year or so attempting to clean up pages as they come across them, but the sheer quantity of obsolete script samples and pages is not reasonable for one person to fix in their spare time. Especially since this also must cover the spambots that occasionally spew forth their garbage on the wiki (and constitute the major of wiki activity over the last 9 years or so). If the wiki can't be updated and maintained to work with remotely modern versions of Unity (and it's clear that it can't be), it needs to be archived and shut down. If you want the content to be accessible, maybe it could get a large warning at the top of every page warning users that the entire wiki is obsolete and deprecated, and just lock all pages as they are so that they don't get further mangled by spambots.
