I turned off some of the notifications as well after my email account went into overdrive....lol.

I think the email thing is great, but I knew to immediately turn it all off. I'm not really interested in getting emails from WA since I'm usually on it anyway. I get enough emails as it is.

Personally I like to receive all notifications into my Inbox. If you setup a filter (aka mail rule) you can get them all re-directed into a specific folder e.g "WA Alerts". Then, each day you can quickly scan what activity there's been within WA and pick up on anything that interests you.

Alternatively, you can do what morlandroger is suggesting and turn off some or all notifications.

Yes, I'm reading this because I got notified via email LOL...
and what morlandroger says below re: account settings..;)

Go to account setting, notification settings, edit and then untick the boxes you do not want.
