When you press one of the “already read”, “reading”, and “want to read” buttons on a manga’s home page, or if you have already pressed one of them and submitted it and press “edit”, more tags for the manga will pop up, I don’t think it’s all of them though
if you're on a manga's home page you can scroll down a bit and find the 'top tags' section, which lists the most highly voted tags.
but that only accounts for a portion of the tags, and usually the unhelpful ones, like "" or "want more!!"
So, is it possible to view ALL of the tags on a given manga?
