Hey there @sekurei
It depends on what platform you're using for your website. If it's something like GoCentral, it currently doesn't have the functionality to allow multiple users. If it's something like WordPress, you just add the user and give them the user privileges you want them to have.
Hope that helps.

unfortunately, GoCentral does not allow for interactivity on your site.
I know because I wanted to have people be able to post on my Blog and was told that's not a function they seem to be all that motivated to provide.
