Howto: Delete account or change linked address?

Hi everybody,

I would like to delete my account to be able to create a new one with my name and my email.
I want to do this, as my Nash exchange account does not match my community account. So when I am logged in to my exchange account in the extension, I can not log in to the community. I also did not find any way to change the linked NEP-5 address in the account settings. Can anybody help?

Thanks, Zap

@Canesin can you help in this case? I know, you have a lot to do these days, so I apologize. Maybe you can point me to someone who can help?
