Yahoo email .co.uk vs .com

[gbinflit]

My Yahoo email ends .co.uk but I would like to simplify that to .com I have tried to open a new account ending .com, but the system just replies that a user already has that username. If I send an email to myusername.com it is bounced back. Is there a way to do this ??
Thanks

No way. That username has been taken for .com, so you have to keep using .co.uk.
