Special rules for templates
Spaces in the name are allowed, e.g. {{train topics}}. The first character (only) is not case-sensitive, so {{cleanup}} and {{Cleanup}}are the same template, but {{cfd}}and {{cfD}}are not.
The template name in general should be short. Many on Wikipedia are abbreviations.
Special rules for namespaces
Only a system admin can create a namespace. Namespaces should be created only after much discussion. The name should be a single word.
