The "Check this box to have yourself notified about replies to this topic." box at the bottom of the message page is ticked as default.
Now as a regular user of the site I can usually see on the front page if there are any replies when I log in so I generally un-tick it before submitting to save unnecessary email messages.
What are other users opinions and should we have a poll to determine whether the box should be ticked or un-ticked as a default?
