Do you mean my profile? or there's some other feature I am not aware of, thanks for your help btw.
Go to your account page and click on "Your Site." This will allow you to create a custom Gemini site on the Midnight Pub. You can add pages, write them in Gemini markup, link them together, and you have a site. If you make your main page "index.gmi" then it will open automatically when someone goes to rosie88.midnight.pub
