It needs to be at User:MrsBunny3/Message Wall Greeting

Tysmmm! Sorry lol, I may just be stupid TvT 👍

Yw! And happens to the best of use lol

Did you get to the page in the screenshot by typing out manually, or the create/edit greeting button sent you there?

I got there by typing it out manually!

So it's not an issue with the feature itself, just wanted to make sure.

You typed the correct form for the old message wall greetings, back when it was a built-in feature, but the current script-based feature indeed uses a different page.
