Hi,
I’d like to create a separate account for someone who will be working on the design of our Invision Community site. What’s the correct way to give them access so they can:

• modify the site’s appearance (themes, templates, CSS/HTML, etc.),

• but not have full administrator access (no access to user management, security settings, or other sensitive admin functions)?

What’s the best way to set this up? Thanks in advance!

Do you have a -testinstall anywhere? You could allow them to do their designing over there and then import it to your community when it's finished.

Thanks! How do I set up a test install? Can I just create it on my hosting with any test domain?

-testinstall

You need to first enter your license key and add -TESTINSTALL at the end — thanks, it works.

Using a test installation for development is always a wise choice. In direct answer to your question though, you can also limit what the administrator can access. Take a look at the following guide, which shows how to create administrators and moderators. You can select "Restricted" on each when you add that user to those areas, and limit what they can see and use. For themes, for example, you can set it so they can see the theme editor on the front end by setting them up as a restricted moderator and only providing that mod function, and similarly as admin, with only the theme section
