I have had the same, Marcilena. In fact, several times. I know this because I get an email asking me if I want to reset my password. I have been told by members on here to ignore said emails. You could do the same. I definitely don’t want you to leave this website.
My advice: use a secure email address. Use a password that you can easily remember but isn’t obvious or easily guessable. Only log in when you’re using this website. And always log out when you’re finished posting. You know this already, but is still vaulable advice.
