Alexa

Hi, I changed my website to WP. I need to enter a code from Alexa to verify ownership. I can use a line of text or <meta name=”alexaVerifyID” content=”xxxxxxxxxxxx” />
This was simple with a website however,
I am new to WP and not sure where to enter either of these. WP was setup automatically through cpanel.

Can I use the editor in the admin section of my wp blog?

Thank you!

Dave
