zeenatsyal on "Does the Feedburner Email Subscription need to be changed after domain mapping?"

Hi Support Team,
I have a bit of a dilemma. I just bought a domain through wp.com with domain mapping form zeenatsyal.wordpress.com to positiveprovocations.com
I have been using feedburner for both rss and email subscriptions for more than a year now. My problem and question is Do I need to make any changes in the feed url for the rss or email subscriptions after this change in domain..or will domain mapping take care of it?
The bigger issue though si that, I have nearly more than 500 email subscribers...and I really dont want to make it difficult for them....I'm hoping there is a simple solution to this.
Please help soooooooooon.. :)
Love,
Zeenat~
