 | This Lua module is used on approximately 265,000 pages, or roughly 12673% of all pages. To avoid major disruption and server load, any changes should be tested in the module's /sandbox or /testcases subpages, or in your own Module:Reply to. The tested changes can be added to this page in a single edit. Consider discussing changes on the talk page before implementing them. |
 | This module is rated as ready for general use. It has reached a mature form and is thought to be relatively bug-free and ready for use wherever appropriate. It is ready to mention on help pages and other Stiles.casa Wiki resources as an option for new users to learn. To reduce server load and bad output, it should be improved by sandbox testing rather than repeated trial-and-error editing. |
 | This module is subject to page protection. It is a highly visible module in use by a very large number of pages, or is substituted very frequently. Because vandalism or mistakes would affect many pages, and even trivial editing might cause substantial load on the servers, it is protected from editing. |
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
This module cannot be used directly from wikitext. Please use the {{Reply to}} template instead.
Usage within templates
{{#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 as of August 2015[update]). If this number of names is exceeded, the parent template will return an error message.
