Hello.
As people subscribe to my blog, they receive the following information in an email:
...so please click the following link to activate your subscription immediately:
http://feedburner.google.com/fb/a/mailconfirm?k=Pv3u-JKp172EaC-ii3iCSJz1ssU
(If the link above does not appear clickable or does not open a browser window when you click it, copy it and paste it into your web browser's Location bar.)
This processes works sometimes. I am wondering if there is a way to make it work consistently.
Thanks for your help.

ICGC,
I went through the steps to generate this mail confirmation link myself. While it worked for me, I think I might know why it does not work consistently. Looking at the source code that Google FeedBurner sends the subscriber, it's written in HTML 5, and it uses the <wbr> tag. This is a new take on the traditional <br>. According to W3schools.com, the <wbr> tag is not supported by Internet Explorer and Opera. So if I'm right about this, I would predict that the confirmation link will work in Firefox, Chrome and Safari but not in IE or Opera.
In any case, you can do what the message suggests: copy the URL and paste it in your web browser's Location or Address bar.
I hope this helps.
I will try it, thanks!!
