There is nothing wrong with having more than one e-mail address.?
I certainly did not mean to imply that there is. I have several myself.
I was focused on Marcio's original question about what to do if he one day woke up to find that the email address which he uses for his Groups.io account had been disabled.
There is also nothing wrong with having multiple Groups.io accounts, as I do. Primarily for the reason Lena and Donald hinted at - it can provide a backup in case you lose access to your primary one. But that backup is limited: since those are separate accounts they do not own the same content.
It has been mentioned many times in GMF that it is good practice for a group to have more than one owner, just in case. I endorse that idea, and usually create a second owner under a second email address of my own shortly after creating a new group. Even better is to have additional owners who are not oneself, if you can identify trustwothy individuals for that role.
