I would like to add my 2c, that this was probably not done in the best way, and that although I think we knew this was going to be the case after the wiki was read-only for an exceptionally long time,hopefully things like this will be handled differently in the future.
The documentation for Unreal isn’t “poor”, but it’s documentation. (well, ok, there probably are places where it is pretty poor, I haven’t been working in the engine for almost a year now, and prior to that 6 month run, several years, so I’m not entirely up to date on things) Documentation is rarely ever as good as community experience. Neither are a replacement for each other, but should complement each other.
That said, I think that when Epic decided it was finally time to drop their support of the wiki, they should have secured someone else hosting a mirror of it. At the very least, providing the archive of it does allow for that, and I’m glad that that has been setup. I just think it should’ve been secured before hand. They also should setup a webserver to 301 Permanently Redirect all traffic to the new host.
With the loss of both Beyond Unreal and Epic’s Unreal wiki, the community has lost (at least temporarily, I think there’s a mirror of Beyond Unreal back up now, somewhere, but i’m not sure on that) an absolutely incredible amount of information spanning decades of experience.
