Just take some HTML/CSS/JS computer Science classes, lol.
Or don’t, if that’s not your thing. I wouldn’t suggest owning a site like this nor hiring people to help you code it if you don’t know enough programming to use a back door. If site ownership changed to someone like PM rather than a company, I’d hope they’d follow through with the open source plan so people like Fizz, KRLW, and maybe even sumwun can work on site changes as well. But I’d rather PM do that himself.
I know the basics, but I definitely do not know enough, nor have the experience to own a sight like this, though I may see what I can do to help whenever PM finishes making the site an open source project like he suggested a while back.
