Registration app: Additional fields

Hi,
if anyone is willing to add the option for additional fields for the registration app, please let us know:

We’re no professional enterprise but a small FOSS-driven collective that runs a solidarity based Nextcloud. That’s why we don’t have a lot of funding, but let’s see if expectations can be met.

Hi Halle,
What you are wanting done is well within my area of expertise and I would be glad to help you out on this.
You can reach me on andrewjohnson.56782@gmail.com
Cheers and Have a great day ahead,
Andrew
