Two more ideas:
1. When you flag an image, you can choose a reason why you flagged that image. This should also be possible with comments.
2. We need the ability to toggle the "Notify me when someone follows a stream I moderate" for individual streams. (For example: If you mod both MSMG and a small stream you just created, you should be able to turn the notifications if someone follows MSMG off but keep the notifications if someone follows the smaller stream on).
