Subpages: Because Why Not?
Here's some examples of subpages, just in case you were wondering what they're for.
A subpage with a subsubpage
Another one with a subsubpage, because 2 is always better than 1
A subpage with a subsubpage that's just fine
A subpage that's not a subsubpage, but still pretty cool
A subsubpage for the ages
A subpage that's just a link, no subsubpage needed
