Test notifications

The engineering team is using this to test notifications.

Will I get a notification now? @"Kan Min-Yen"

Seems like this works now.Testing first without mentions.

Trying again with some mentions now. @"Justin Ng" @"Zhao Jin" .

I like how this system brings up a list of users after typing in the @ sign.

Yes, I do get an email. @"Kan Min-Yen" do you?
