This is a test of a formatting bug.
Hello! This is a block of text that has been italicized with underscores. I am going to link to a URI that has underscores in it. [Here is the link](https://en.wikipedia.org/wiki/SDSSigmaseries). You can see the rendering is broken.
This is the markdown above:

The workaround is to use * to italicize instead, so it's not a huge issue.
