Hello fellow vivohodles/masternoders/miners

In one of the announcement post there was a link to a kind of Masternode checker, that would update on email if mastenode for some reason is down
I have searched trough posts in all pages to try to find it, but somehow i cannot find it.

I know there is a mobile version, im not looking for this. Im looking for the mail version,
and... if someone using this, is it working good?
