##About
Complaints on meta were raised about the threshold of 15 chars for comments, and even though many people agree that it shouldn't be there, this request was status-declined.
Using this script makes even adding blank comments possible.
Relevant meta posts:
Can we get rid of the threshold of 15 chars for comments? Why the 15 character minimum on comments?
