Logging onto twitter

[Svrider]

I have forgotten my username and password for twitter
It won't let me register as my email address is already used
Where is the forgot password option
I'm on iPod
Thanks

Anyone??
School have "wisely" decided twitter is to be the main mode of communication!

Is this it?
twitter.com/account/resend_password

Thanks
That's worked

Seriously? The school is communicating by twitter? That seems a little public.
