@Piano-Dad Yes, I know how to reach you. We do have some folks who signed up and who have either never posted or haven't posted in a long time. I don't want to pester them with updates unless they want to be pestered.
You can choose the option to hide your email address from casual observers, but people with superpowers can see that info. Mostly I just wanted to know who wants to be notified if we have a major outage.
Additionally, a few folks who signed up early might not have had to provide an email address to create a user ID because registration was open and didn't require authorization by an admin or mod. Eventually we locked the door and deleted all the spammers who had signed up while this was the backup site. I just wanted people to check their profile and see if they have an email addy where they can be reached.
