To set email and other notifications.
Click the notification bell in the header, a window pops up with settings at the top right to bring you to your board settings. You can also get to this using your Profile when clicking your username.

To add your email: Click Profile, Edit Acct settings and enter your email.

To add notifications: Click Board Preferences then Edit Global settings. Please allow Admin to email you for important issues. Thanks, Admin.

Thanks!

To get to where I can edit my email, I have to do this (from my desktop computer):

Go to the Shule dropdown menu thing by 'Private messages' (it'll say your username instead of Shule) -> Click on Profile -> Click on Edit profile (by your username) -> Click on Edit account settings (on the left) -> You can edit your email address there.
