If you don't want to be notified of every post...

I noticed that I am receiving an email every time anyone posts on a thread I posted on. If this is happening to you, and you don't want/need the emails, go to your profile, under 'preferences', and click 'NO' on the option that says you want to be sent a notification email every time a post is made.

It looks like that might be the default setting, so each user would have to undo it for themselves.
