I noticed that on some wikis the system messages have been modified based on the theme. Like on the Harry Potter wiki it will say "You have an owl" insead of "You have a message". So I decided to do a test.
On our wiki, it will now say "edited by a toon" instead of "edited by An anonymous contributor". This is located at MediaWiki:masthead-anonymous-user. Do we like this? Yes or no?
