We would like the ability for users to be able to submit a post anonymously. Our use case:

We are an online school and use our Zendesk Help Guide as a community space for our students to share resources, make feature requests, give feedback, etc. We also ask our students to give feedback through and Airtable form, because they can do so anonymously there. We'd love to consolidate our feedback from students to be able to have 1 source of truth for all of our information, but we don't want to lose out on the feedback we get from students anonymously. So, we don't want this to be a non-signed in user, but just a checkbox where a user can say they'd like to post their message anonymously and then their name is masked.

It's very important for our school image that we build a sense of trust and transparency around the feedback we are getting and addressing it openly, but we can't do that if our students don't feel comfortable giving us the feedback to begin with.
