Hi Pingdom folks
I had an issue yesterday when trying to add alert contacts, which resulted in my raising an unnecessary support ticket.
The reason is that users and contacts are added in the same screen (see screenshot 1). However if you have run out of users, as I had, you are greeted with a great big "You're out of users" graphic in the modal box. Then, if you don't really know the difference between users and contacts anyway, it's not really clear that you need to click Continue in order to add a contact.
I think it would be less confusing/more intuitive to separate out Contacts from Users, maybe in the left nav (see screenshot 2)?
