Just recently, I discovered how to leave a clickable link at the end of a comment and I found a really easy guide to help me do that. You just type this at the end of the comment, easy peasy:
<a href="http://yourwebsitehere">what everyone will see here</a>
For reference, this is what I type at the end of the comments I write:
