Do you have a list users on your website called subscribers?
I decided to check out my user page on my three-year-old website for the first time since I set myself up as the admin.
To my surprise, I saw that I had over 1000 users listed under the Role column as subscribers. The Email addresses ran from a to z. Is this normal? If so, how can this happen? If it is not normal, what do I need to do about this?
