Create sites and/or users or add users to existing sites by uloading a CSV file. Tweaked and updated from the WPMU Dev Batch Create plugin.
- This works on modern WordPress and PHP as of writing this (WP 6.1.1 and PHP 8.1)
- It uses email address, not username as the unique identifier for looking up Users. If an email is already in use, it will find the username that corresponds with that email and proceed.
- I've disabled welcome emails to users who are added to sites.
- I've removed XLS support and streamlined the instructions page.
- The CSV template is tweaked a bit.
