Now, I for one don't typically like sites that are over-moderated. I like to see the thread flow, isn't that the whole point of a web forum? Well, recently I have seen some behavior that I don't particularly care for with people mass deleting their threads and posts, brought on by other members replays to their threads.
Because of this I have added a new feature and it is up and running. Test it out, create a new thread, below the thread body add the members you want banned from your thread, It should display to you and the mods who who you chose to ban from replying to your thread. The person banned will get a message when they attempt to submit a reply that they are not allowed to reply.
This allows the mods and admin the chance to try and stay out of the middle of an argument between members.
