Long time listener, first time caller etc,
Here's the quick hack to get around the multiple choices email. Find the last part of that link, eg:
A=ant1234567890&E=bob@myemailaddres.com&P=topsecre tpassword
Now paste it into a URL after
http://www.underworldlive.com/index/login/activation/?
so for my example
http://www.underworldlive.com/index/...secretpassword
click the button it gives you, and you're off!
