Wow, @mwatson2 ! This is exciting! Here’s a link to our sample chapter forum.
Regarding graduate student submissions, do you have a content management system in place for this? It can be as simple as a shared Google Drive folder with a spreadsheet that tracks submissions where students can share their work. We will talk more about licensing in July–I also recommend making sure students have licensed their work. Here’s a very rudimentary Google Form example I use for our Undergraduate Student Journal at CWI to collect author information and licensing permissions.
