How does one add friends. I think I'm friends with you, though I'm not sure how that happened. Maybe I friended you but I'm baffled about how to do this

Do you get this reply? I'm not sure how to navigate this thing???

I'm still learning how to use it. It will only allow me to write short relies....????

I found your site!!! I'm still not sure about this site and I find it hard to navigate so I'm sticking with Facebook until I figure it out and then I'll probably stick with Facebook as well as this site.
