Today, I decided to try to do my own forum website (using some simple websites for make forum websites, or smth like that)

But I'm kinda confused at doing it, like, I don't actually know if I'm doing it correctly or wrong, or something like that

So please, someone tell me some tips (or other) for do in my first time doing a forum website.

(Also, if you want, here's the website's link: https://25chan.foroactivo.com/ )
