There should be an email notification when someone post you something.

After all these years of silence, an email notification system was added.
It will be modified later on - users will be able to turn it on/off, but it will take a little more time.

If I had to dedicate this feature to someone, it would definitely be MrCed, since he was our local notifier until now and did it orally.

NOTE: The email notifications will not be sent if the sender is on "invisible list". So if you do not want to be bugged by someone on your contact list, this is a way to reduce the amount of email notifications.
