There are two terms in my thesis that I'm using throughout the entire work. They have been added to the glossary for that reason. However, by the time I got to chapter 4 or so I've stopped writing them as PDF hyperlinks (so that they can jump to the corresponding entry in the glossary) because I got really tired of it.
My assumption was that by this point the reader should know what the glossary terms mean.
Is this okay or should I use glossary hyperlinks as much as possible?
