At the moment I am creating severeal templates in this wiki here (MW 1.31.3). One existing template - because its set to german langauge, they are called Vorlage; this means template - one existing template is called Vorlage:NIV-II with an upper case I at its end. Then I want to create another template called Vorlage:NIV-Ii with a lower case i at its end. I entered this Vorlage:NIV-Ii in the search field and immediately the Vorlage:NIV-II template poped up. After that I created a template named Vorlage:NIV-Iie. This worked fine. Thereafter I moved the Vorlage:NIV-Iie template to Vorlage:NIV-Ii. This worked fine, too. Now both templates are alive and kicking. The question is: why was I not able to create the template with the lower case i in the first place? Is there a little gremlin at work?
Many thanks for an illuminating answer in advance!
