Hey there,
It seems you’re looking to login to your the Groupanizer site for your group - that’s great!
Every group has their own specific url for their site, so you won’t be able to login here.
Instead, you’ll want to find the url for your specific site - this is often something like “yourchoir.groupanizer.com”.

If you’re not sure where to find your group’s site, check with the leadership of your choir/chorus.

Why do we use separate urls instead of one url like facebook?
This allows us to keep all site data separate and safe, increasing the security and privacy of your personal data.
