How can I self host this, and are you aware Shibboleth is a very old and actively used, well known software? I was quite confused seeing that in the dropdown.
We were not aware of Shibboleth single sign-on before we launched, and someone noted the name collision on our Show HN thread. If many people are confused about this, we would certainly consider a different name. The development team wanted a non-generic name (e.g. CAPTCHA), and naming has proved a challenge for us, so if you have any suggestions, please let us know.
