I am new to WordPress, and someone else has setup my site. I want to set up some internal links to other pages on my site, which have been set up in this format: [get_permalink id="174" title="our services"]. I want to set up some further links, but can't figure out how to do it. How do I find the permalink id #? And is there some way to use the 'link' button on the WordPress editor for this?
