Every time you edit a page on wretchedyoutubevideoswiki and on every new wiki when VisualEditor is installed, the "Welcome" message appears instead of only appearing the first time.
The message is:
Welcome to Wretched YouTube Videos Wiki Anyone can edit, and every improvement helps. Thank you for helping the world discover more!
This can be replicated by editing on wretchedyoutubevideoswiki or on a new wiki when VisualEditor is installed.
