Free Members Area

Hello,

I’m looking at creating a members area for my WP website, so people can register/login to view certain pages of the website, i.e competitions, special news etc… I want the membership to be free as well so noone has to pay to login or anything! I have looked around and cant really get the hang of any to be honest. I also need an easy install one too! lol All help would be greatfully appreciated!
Thank you 🙂
