especially admins.

feedback from admins:

• restrict language code input to numbers, letters and - (done)
• worried about users creating projects and not using them
• users shouldn't be able to create projects on their own
• wesay projects should use the dictionary suffix (done)
• consider faster feedback on duplicate project codes (before submitting the form) async validate duplicate project codes on creation page #257
• projects get created when some already exist let users request to join a project in their org #258
• explain what some options mean, especially retention policy
• a language picker for the language code would be great

We'll discuss these points as a team.
