How do I remove my emailaddress from a post?

It looks like that’s the username you chose.

There’s not a way through the web interface to change usernames, you would need to modify it in the database or create a new user and reassign the posts to that account.

See https://www.ads-software.com/support/topic/change-user-name?replies=4 for reference.

Thank you for the feedback. I found the fix

Go to users, edit, change the Nickname, Display name publicly as – change from the drop down to display the nickname, Save and you are all done.
