I accidentally clicked the "unsubscribe" button for the email alerts I've been geting when mo oppnent moves. For the last few days I've been trying to find a way of reinstating the email alerts but haven't found anything yet. How do I get them back?

@samotomas

If you are on a computer, click your avatar icon at the top right corner of the screen.
Then click 'my settings', then 'notifications'.
You should be able to turn email notifications on or off there.
Make sure you go to the bottom of the page and click 'update' when you are done.

Hope that helps.

You can do so here :

My Settings >> Notification Settings >> "Automated move notifications"

Notification Settings

edit : Or as @mwmiller said. ☝️
