I made a simple forum system with @18001767679, and you can find it at https://forum.phpthings.repl.co/. (don't judge me for using PHP, I just used it to try PHP.) You can login and post topics but there is no password reset.
@programmeruser why? I'm not a professional hacker too, so IDK much. Anyways, cool site (needs css tho). +1 from me.
