It says my email address is invalid.

Please ensure that you are using a valid email address, and you
are typing it in correctly. We do not support email addresses with generic prefixes (e.g. info@, webmaster@ etc.) because these are typically used for organizations or businesses and are not allowed to be used for personal Gnommie accounts. Email addresses are offered for free by many websites (e.g., Gmail, Hotmail, Yahoo!).
