At a risk of sounding horrible (I'm not), did you finish writing the article? I mean, if you don't listen to all ideas that people have to offer you, then you're bound to dismiss a good idea at some point.
It didn't seem to complain with my (UK) address, and I got the "confirm your email address" mail through and that link worked fine. This was one or two hours ago though, so there may be a new bug or the page (or the DB behind it) may be under sudden load if the link has hit high volume sites like slashdot.
I'd report it to them if I were you, though please make the bug report much more detailed than "it didn't work"...
There is no "hacker style" to filing a good bug report. But I have a bee in my bonnet about bad ones - I often get the equivalent of dropping a car off at the garage for repair with just a note that "it makes a noise".
Same has happened to me, no matter what options I fill in, or whichever browser, it just redirects me back to the same page with the radio buttons deselected. Maybe it doesn't like the UK?
