DO NOT MARK FEDORAFORUM MESSAGES AS SPAM!!!!!!!!!!!!!!
When you do, those of us who want to receive forum notifications cannot, as Google aggregates the spam data. When you mark the messages as spam, it not only starts putting them into your spam folder, it put them into the spam folder of EVERYONE, even those of us who want them.
It is not hard to change your subscription settings. Please do so. If you're smart enough to run Linux, you're smart enough to change your subscription settings. Don't destroy the notification system for the rest of us who rely on it.
