Turn off Post Information in Panels and other Content Types

For months I had wanted to turn off the post info in panels - you know the bit were it says 'Posted by admin on ....'. I didn't want it but it appeared every time. since all my products are displayed as panels it just presented some useless info that cluttered the screen up. Then, by accident I found out how to switch it off! Cool ...

Administration > Structure > Content Types > Panels > Edit, and then click on Display Settings and uncheck 'Display author and date information.' Click save and it's done!

It even removes all the Post informations on all the panels you have created previously.

This same process is used to set all the defaults for all content types, including blogs, pages ... etc.
