Need a little bit of help with a note wiki.

[Sam1]

So I am creating a note wiki for the people in year 12 doing IB with me. I am giving membership away to all the people in my english class, but to cover costs (of hosting and domain) I decided to charge $2 per student for a years access- which I think is super cheap because I am not aiming to make a profit from this.....

Anyway my only issue is how to make a wordpress page login only- i.e. you have to login. Any ideas?

Currently the site is here: stpsib.com

Doesn't matter- I managed to find a plugin for this
