About error messages
Dear Tardis Wiki Admins,
please, do not hide or obscure error messages.
This prevents the users from getting helpful information when they make a mistake. And as such is considered a breach of our Terms of Service.
Also, that's what broke Special:Promote.
You're free to style the .error class to fit your wiki's custom theme (which is awesome, by the way), but please make sure the messages are visible and legible.
Thanks!
