Where do I go to see if my questions got any answers?

This one: my icloud emails sent from my iMac to gma… - Apple Community

1. You would get email notification (unless you select to not receive such messages),
2. In your personal site profile, under ‘My Subscriptions’, you can find a list of threads in which you have participated.

Furthermore, the Filter to your left in My Subscriptions may have to be adjusted to “Authored,” for you to see the threads you’ve created.

If you only want to see threads you’ve participated in tap “Participates.”

And lastly, tapping “Following” will show you all threads you’re following.
