I don't believe this is possible at this point in time. The only option that I know will show you registered users is to require approval.

beyond that the other option would be to copy the core registration controller (concrete/controllers/register.php) to /controllers and add a few lines to send you a notification.

I'm clueless with PHP. I can copy the code provided, but cannot create the mail template from scratch. Anyone already have something?

Here's the one I used if you want to try that.

Just add it to your /mail folder (not the one in the /concrete directory). Just make sure you remove the .txt before you upload.

Let me know if you have any problems.

Thank you! This does raise another question, though.

Were the other files and code mods supposed to be done in the concrete directory, or in the main directory of the subdomain the site is hosted in?

All of these modifications should be done outside of the /concrete core folder.

If you put them inside the concrete folder - I would just move them out and delete the ones you placed in the concrete folder.

The config.php file is already outside of the /concrete folder so (assuming you put the file I left in the /mail folder outside /concrete) you should only have to move the application_user.php file out to the /models folder.

I hope THAT sentence wasn't too confusing!

Awesome! Works perfectly!

Thanks for all your help!
