I installed wp-united and is working perfect.
I have enabled cross-posting and user-integration and everything works fine.
The problem is that when guest users (not logged in) read an entry about wordpress and want to leave a comment, they log on from wordpress.
Is there any way that when they press "login" button send them to the login page of the forum, and in his absence the forum registration?
In short, what I want is that users only register and login from the forum, and eliminate all access by wordpress, but keep the comments under wordpress entries.
Is this possible?
