Pages here were once part of the main site, but have since been abandoned, and will no longer be updated to be compatible with the main page.
Reasons for abandonment can be numerous, but usually it just boils down to me no longer having a use for it.
I have updated these pages slightly to make them work when I first add them here, mainly due to me using relative paths for a lot of these, for some reason, but after that, they'll most likely be left to rot.
