Hello,
And again we have a new extra, yeah!
From now own you can insert your own <head> content into your homepage.
Here is a short description of the extra:
This extra is meant for more advanced users.
Sometimes it is helpful to enter contents in the
<head> section of your website .
An example: some external website services, such as the
Google Webmastertools require you to verify the owner of the website.
So that Google can verify you as the owner of the website, a HTML tag is provided for you when adding your site to the webmaster tools, which you then have to insert into the <head> section of your website.
And this is exactly what you can use the extra for.
This extra can also be used to integrate JavaScript or the like.
Have fun!
