bbPress.org

Nothing is broken. I do not know what I am doing. Documentation is not helpful.

I dedicated a MultiSite subsite to the forum. WP 4.1/BBPress 2.5.4
I have never set up registration/login on any of my sites.
I do not want the site to require a login.

1.) I have no idea how to set up the forum logging in, at all.
2.) Many of my users do not have email accounts. How can they register?

Any input or direction would be greatly appreciated.
Thank you
