Disable positions?

Continuing with the design of my site and am using the template Destinations.

I would like to disable the logo position, and user4 user4, is this possible you ask?

open index.php of template. FInd this:

<jdoc:include type="modules" name="logo" />

and remove it.

You can find similar for user4.

After that if you want to remove them from administration so they don't appear. Open templateDetails.xml and remove:

<position>logo</position>
and
<position>user4</position>

prom <positions> element.
