How to become part of a user group

I am wondering how to become part of a user group (for instance one's country, one's age etc.)

I see all these things on the forums about page and in discussions, but I can't find them.

ArDanZ11 on the forums about page

Where do you see that on the About page?

I've been here for almost five years, and if this forum software has that feature, I've never seen it used.

ArDanZ11 Not sure what you mean?

DaveTheCoder Well, the platform has user groups and is used for setting different types of permissions, for example Verified user, Mods, Admin, etc.

MikeCL I don't recall seeing any Mods, and just one admin.

ArDanZ11 Currently the only mod and admin is me. I meant more as to explain what the user groups are used for. 🙂

I think that is how it has to be - 1 mod+admin, no need for anything else.
