Hi. I use the thread prefix option in sonnb's profanity filter to hide threads marked as NSFW for those who have not checked option in their preferences. To extend this concept, I would like a modification that would let us mark threads as 'Member's Only' for instance, hide from guests. I would prefer to have a 'Member's Only' thread prefix instead of creating a Member's Only forum. Reason I ask is because making my site private was one of the hugest mistakes I've ever made. Kinda hard to recruit members from social-networking sites if they can't tell what my site's about... I will donate for this project.
