I’ve learned that readers attempting to post comments find themselves blocked by a screen with the following message:
That email address is associated with an existing WordPress.com account, please log in to use it.
I know neither know this means or why this is happening, and my attempts to resolve have led nowhere. If any WordPress users have suggestions, please email to email@example.com. Meanwhile, I’ve sent a request for help to WordPress itself.
I find that to get past the screen, just type anything at all into the email address line of the comment submission form, and the comment will appear (without an email address).
Sorry for the inconvenience, and thanks for your patience.
As for Saint Patrick’s Day, I recommend reading “8 Insulting Ways People Act Irish on St. Patrick’s Day” by Luke McKinney.
