Fandom is currently trying out a new Walkthrough teaching aid for new editors. Apparently, results so far are much better than expected. After trying it on a limited number of wikis, they would like to expand the number using it. Since you are hoping to recruit new editors, I think it would be a good fit here. It appears on the rail, you can what it looks like here. Is this something you would want to try on this wiki?
The current testing phase for the walkthrough teaching aid that was enabled for this wiki will be ending tomorrow and eventually disabled. Depending on how it performed, it may become a standard feature on the United Community Platform. Let me know if you have any feedback on things you felt it did well or poorly within the next 24 hours.
