The DCA extension, short for Discourse Community Authentication, is my first open-source extension! Over the next few weeks you will see many improvements to code and a great amount of customization! If you come across errors, please file an issue report as I did make this in two-three days.
Please respect my wish that you do not take a snippet from this extension, create a one-block extension for yourself, and then not use my extension. More customization will come in the future, just be patient <3
Issue has been fixed. Thank you for your patience.
