Template:High-risk Template:Module rating Template:Module rating This module is used by {{Reply to}} to trigger a notification to one or several registered user(s) you are replying to in a discussion.

Usage from wikitext[edit source]

This module cannot be used directly from wikitext. Please use the {{Reply to}} template instead.

Usage within templates[edit source]

{{#invoke:Reply to|replyto|<noinclude>example=example name</noinclude>|max=maximum number of names}}
  • The |example= parameter sets the name that will show when the template page is viewed. This parameter should be surrounded by <noinclude>...</noinclude> so that it is not transcluded with the parent template, and the parent template will show an error message if no names are specified.
  • 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 Template:As of). If this number of names is exceeded, the parent template will return an error message.
