I am getting an odd behavior. I just updated to Subscribe To Comments Reloaded version 2.0.3. This morning and yesterday morning I received emails from the site with subject "Manage your subscriptions on Jeffs Classic Arcade" and message "You have requested to manage your subscriptions to the articles on Jeffs Classic Arcade. Follow this link to access your personal page:" with a link to a management page that shows no actual subscriptions.
The email address it sent the email to was my work address, which as far as I can tell has no subscriptions.
