As I promised:

This version of hack does not display the thread subscribers while you read the thread. Instead it displays a link "Display Thread Subscribers" next to "Subscribe to This Thread" and when you click it, a new window opens and display your thread's subscribers.

By default this link will be visible to Admins, S.Mods and Mods only but if you want to see it other members too, holler and I'll give you the code you need to change. (Please notice original hack displays the thread subscribers in the screen where you read the thread AND to all thread viewers)

Ps. I appreciate if someone who applied this version post a screenshot, thx..
