And most of them are registered users who want to flame someone then go back to being "normal".
So forcing registration isn't the solution.

How about a link that sends e-mail to all the mods or something that the mods can easily click on so that those who want to post something important can but still remain anon?

The other thing I want to know is if someone spent their time writing some code for this, would it get used? Are you open and able to test & modify this code? If a patch file was generated can you figure out how to apply it? Is this the "full version" for the software? Is it the latest release? Has there been any mods applied so far?
