The How-To Geek doesn’t allow just anybody to leave any comment they feel like. Because this site is dedicated towards helping people, only helpful, constructive, on-topic or interesting comments will be approved.
Update: I’ve decided to simplify our comment policy:
1) You comment at the pleasure of the king.
2) Any offending comments may be deleted for any reason.
3) Please be helpful, constructive, on-topic, and interesting.
Just keep in mind that the How-To Geek is here to help the readers(including you), and you should have no problems with the comment system.
