My Email is displayed in Comments

Hi

I am the admin of a site and the first post I have created lists my email at the top of it. so people can click on it and email me – I don’t want people to have access to my personal email ! I have tried to edit the post but it has not changed.

How can I removed this from the post ? Surely it should not be displayed ??

Thanks
