Organization Labels provide poor user experience
Description of problem:
Creating an Organization leaves the creation of Organization labels up to the user, when there are different rules for names and labels. The rules for acceptable characters aren't explained, and aren't caught until you try to save the Organization.
Have field labels disabled and auto-filled, replacing any characters that shouldn't be there with underscores, so that it's always a valid name. It seems like a nicer way to approach the Label field. As far as I know, it doesn't seem important to let users name it themselves.
If we need to let them be user-editable, client-side validation should happen before trying to save it.
