Go to "my settings" on the right side of your page (it is below the
"my friends" and "sign out" links). Go to "Email" on the left side.
Uncheck everything that you do not want to receive notifications for.
Also click "clear my follow list" (It's a box with those words
inside). OR, if you do not wish to receive any email notifications,
click the last box, "None, I don't want to receive emails from the
official Twilight community." Make sure you click "Save" before you
leave the page. If you're getting email notifications for every thread
started and discussion, click on the forum tab and at the bottom of
the page click the “stop notifying” link. Then, go to the top - where
you see 'view' and a drop-down box, change the box to sort the forum
by “discussions”. Next, go to the bottom of the page and click the
“stop notifying” link there.
