I have a HD16 on v.4.0.1144. It's spring again and I need to provide shared access for the sprinkler company to open my system.

In the past, I shared access and I thought that there was a button on the main page but I no longer see it! Am I wrong about the button?

I did eventually find the shared access page by going to 'https://my.rainmachine.com/shared' but I'm not sure I will remember this every time I need it.

Another question... I see that the shared access expires in 7 days. Is there any way to extend this so that I don't have to always remember to send out an invitation? Ideally, I would like to have the ability to provide access for an unlimited time but also have the ability to cancel that shared access should I change sprinkler companies.
