Can you give a couple examples? I can't think of any accounts that don't allow an email change.
Not everything is a phpBB forum.
Also:
> Select Google Account email. If you can't open this setting, it might not be possible to change your email or username.
> If your account's email address ends in @gmail.com, you usually can't change it.
Say, for example, systems that directly expose your email address as the identifier that can be used to reach you. "Send money to saagar@saagarjha.com [using our service]" kind of sites.
