I just noticed that on the exported cartridge files, it says "www.pico-8.com" on the top (the .p8.png images). I tried going to that address, but I get a 406 error. That should probably be fixed somehow...

Works for me currently, redirects to https://www.lexaloffle.com/pico-8.php on Chrome

Oh, yeah. It's working now. That's weird.
