A long time ago, we clicked the “Anybody Can Register” box in our blog settings. Some of our friends were writing guest blog entries, and it was easier for them to create their own log-ins and then adjust their permissions.
But we have not had a new guest blogger in a very long time, and the function is now mainly — perhaps only — used by spammers who hope to be given some sort of additional access to the site.
So the “Anybody Can Register” functionality is now shut off, and we have undergone a user purge — if I do not know who you are, you no longer have a log-in.
Sorry if you’re real, and you liked having it, but it did not actually do anything in the first place.
