Add Sept. newsletter to site

[BekahHW]

Issue Context

Every month, we try to get the newsletter up on the site within a week of sending it out. Currently, we're moving them over "by hand."

You can look at the existing newsletters ( src > newsletter > issues) as a kind of template. The sections are all the same. The content needs updated, and sometimes that changes the way things look, for example, your list may have fewer items.

Add the latest issue using the format from the past issues.
If you have questions, please let us know. We're up for pairing if anyone wants to walk through this!
