You haven't really gotten into my point of why I think message walls allowing wiki text is beneficial. If there cannot be a message wall function where I talk to people about their editing or actual things happening on the wiki, but only the fiction or unrelated topics, I think I will start to engage less with users and ban more, while editors will not improve and grow with the community. In that case, there needs to be something just like the message walls that can work with the code given on wikia and on the articles, purposed for helping out or warning other users. Mini sandboxes, as you will.

I was trying to make a random Sandbox on the wiki you linked, and was unable to create categories with the steering wheel emoji provided on th3 right side. Why is that?
