Hi again,
I wanted to let you know that I have followed up with our developers regarding your original site:
http://katcameronillustration.wordpress.com
And they have still been unable to find any additional followers predating the original migration, though additional subscribers have signed up for your original site.
If you'd like, I can re-migrate these new followers, and to prevent additional people from signing up at the original site, I would be happy to provide our product Domain Forwarding, free of charge. This will make anyone who visits katcameronillustration.wordpress.com be redirected to your new site automatically.
