Disregard All Emails From Me.

Someone has hacked into my Gmail account with my password and sent awful emails to a bunch of people. They are a reader of this blog and they are sure not helping things. To Mario, Chris, JV and Dave, the emails you received are not from me.

Can someone please tell me how to switch the email associated with my blogger account? I know this person is part of the blogosphere because they have read my comments and posted them in the emails. I hope this doesnt hurt things around here.
