Usage within templates

{{#invoke:Hidden ping|hiddenping|max=maximum number of names}}

• The |max= parameter sets the maximum number of names that the template will accept. If not specified, it defaults to 50 (which is the maximum number that Echo currently supports as of August 2015^[update]). If this number of names is exceeded, the parent template will return an error message when previewed.
