On the new site, you need to login with a username and password, not email address and password.
If you were a member of the old forums, your username is the name that was shown by your posts. If you don't know what this name was, use the Send Password form. Just enter your email address, and you will be sent an email containing your username and a new password.
Note: the email address you enter must be the one you used when registering on the site or old forums. If you can't remember which one you used, you'll have to contact us, giving your full name and contact details, and we'll try to match you to an existing user account.
If you are sure you are entering your username correctly, the best solution is to get a new password. Use the Send Password form. Just enter your email address, and you will be sent an email containing your username and a new password.
If you can login but keep getting logged out one page later, please ensure that cookies are enabled on your browser.
If you can normally stay logged in but occasionally get logged out while using the site, please let us know. We're aware of this occasional problem and are working hard to understand why it happens.
Go ahead and contact us. But please describe step by step exactly what you did and what happened as a result. "I have had problems trying to login to the new site" is not enough detail for us to be able to help!
