<p><strong>How to find the feed ID for this site at Feedburner:</strong><br />

Login to your Feedburner account, click "My Feeds" -> Title of the feed in question -> Publicize -> Email Subscriptions -> Check out the two textareas. 

In the bigger one of the two textareas your ID appears as: <br />1) If you have an <strong>old feedburner.com</strong> account:  

www.feedburner.com/fb/a/emailverifySubmit?feedId=<strong style="color:green">1234567</strong>&amp;loc=en_US<br />2) if you have a <strong>new feedburner.google.com</strong> account: 

feedburner.google.com/fb/a/mailverify?uri=<strong style="color:green">bytesforall/lzoG</strong>&amp;loc=en_US<br />The green part is the ID that you need to put here.</p>

<p>Is this a feedburner.google.com account or an old feedburner.com account?		

<p><input id="google-or-feedburner" name="google-or-feedburner" type="radio" value="google" <?php 

if($google_or_feedburner == "google"){echo " CHECKED";}?> /> New feedburner.google.com account</p>

<p><input id="google-or-feedburner" name="google-or-feedburner" type="radio" value="feedburner" <?php 

if($google_or_feedburner == "feedburner"){echo " CHECKED";}?> /> Old feedburner.com account</p>

			<input type="hidden" id="subscribe-submit" name="subscribe-submit" value="1" />
