Possible security risk - forum are not secure by using http instead of https

I noticed the forum is not using the industry standard of https, I'm sure you guys already know about this but I'm curious as to know why, since http is unsecure and widely regarded as a security vulenability that can be exploited. I do not believe it is difficult adopting or having any benefit to use http over https. Which is why almost no website use http in 2018 anymore.

Right now, forum traffic are unsecure and not encrypted...
