Also, what member login plugin do you recommend?
I was asking about he forum that we are writing in now.
As I said, right now this forum only accepts guest posting so there is no need to login.
Install bbPress. A page will be created automatically. If you need to add the forum to a custom page, you can use bbPress shortcodes.
