Allowing Tags
I have, for a while, known that tags are often an important part of any website. I did not know exactly how to implement these tags within the GitHub pages system. A little searching and I have found this method which appears to be the best approach as it still makes use of GitHub pages and Jekyll.
I have currently updated all of my posts so that they include a number of tags. I will soon attempt to update the site so that it can make use of these tags.
