I moved the Forums Sunday evening and since then there seems to be a aproblem with certain ISP's that use Proxy Servers to allow their customers access to the Internet. The worst culprits seem to be AOL, NTL FSnet and BT. Once their cached files are refreshed it should resolve the situation.
Paul when you signed up you provided a password which is encrypted in the cookie so you wont be able to read it... not too sure what the encryption level is but it is only there to ensure it is only you that posts using your username.
