subscription problems

I have received a couple of complaints about people subscribing to this blog via email but being unable to receive the updates. I checked with Feedburner and they have this recommendation:
===================
Some people have problems clicking on the link provided in the confirmation email. You might want to ask the subscriber to, upon receiving the confirmation email, just after they sign up, to copy and paste the link into the browser. It should take them straight to the confirmation page. Then it should work.
===================
Hope this helps. Let me know if you're having problems.
