I'm not allowed to sign up on there says I cant use my hotmail based email addy
I haven't tried it, but try www.mytrashmail.com, it's a temp email address. Failing that, spend about £10 at 1 and 1 internet and get a web address for 2 years, it comes with a couple of email addresses.
edit - tried mytrashmail but it doesn't work. Try getting a free www.cjb.net redirection URL and setting up the free email through them. That does work.
