Wordpress Feed Creator Name Tag Full Name Instead Of First Name

I am parsing a Wordpress feed in my iOS application. I don't know much about Wordpress and its customisation. The feed shows the author name as below:

<dc:creator>andy</dc:creator>

while i want it to show the full name of the author in the feed like:

<dc:creator>andy rubin</dc:creator>

Can anybody point out where i can go to do that. Thanks!

Solution

Open your Wordpress dashboard and go to Users > All Users and select edit for the user for which you want the full name to appear. You will see the option "Display name publicly as". From drop down list you can choose the full name.

In the feed you might still see first name but once you parse it in your iOS project, it will show you the full name.

Hope this helps!
