Thank you. There is also a small Python app to kick off archival requests if the CLI is more your thing (I find it helpful when I need to generate a list of URLs and then pipe that list to savepagenow with a sleep in between runs to be gentle on the Wayback API).
I think I prefer to use the savepagenow@archive.org email address, best leave it up to archive.org to schedule the archivals. Its also more convenient to paste some HTML into an email and have all the links archived.
