If you are a paid subscriber, go to the upper righ

If you are a paid subscriber, go to the upper right corner of ihub and click on 'settings'. Then down the left side click on 'cancel' under the message board subscription section.

If you are not a member, I don't know if you can have your page deleted. But I know you can get 'booted' if you just publicly tell ihub admin to go F... themselves, lol
