WP Network Multisite "mu-plugin" for user activation key removal or approval.
I've used this over a few years on the odd occasion.
This is a great help to fix issues with blocked email invites and user registration.
Simple and does exactly what you expect.
This plugin is really simple and great. It just get the job done. :)
Brilliant and simple plugin thanks again
Clean and simple! just great! Thank you!
This not only allowed me to delete inactive accounts without waiting 2 days and activate them personally if I need to send login information directly to the user.
Thank you for this wonderful plugin.
This plugin in saves time and hassle allowing one click user activation key to be deleted instead of having to go to the database in myPHP, search for the user and delete the line.
