MEV has written that this should be happening for our subscribers:
Feedburner issue: You currently have 2 different feeds setup through feedburner. We created a redirect for the old feedburner URL to the new one and all RSS feeds should be working properly at this point.
•All old subscribers will be redirected to the newer feedburner
•All old registrations are tied to the old URL which is not visible to us because it is linked to a different gmail account than the one you have given us access to.
•All new registrations will be linked to new URL in the account which you sent us
Please let me know.
