I just installed this and think it will be very useful in a number of different threads. Part of my forum contains sports threads and sometimes someone will start a thread only for fans of a particular team. Of course, almost immediately other members come in and start to trash the team the thread was made to support. Now with this, I can give the thread starter control over his thread and take the headache away from the moderators.
If I could make one addition to this mod, it would be to grant the ability to ban a member from the thread in the Threadmin part of the mod.
