Kasia and i are having this problem, with replies to threads being emailed to you.
Do you want to remove this?
1. Make sure that in your profile, you have "Replies emailed to you" clicked on NO.
2. When starting a thread, make sure on the bottom of the page you UN-CLICK "Notify me when a reply is posted"
If this doesn't work, let me know and i'll try find another way around it.
