This module is rated as beta, and is ready for widespread use. It is still new and should be used with some caution to ensure the results are as expected.

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.

Implements {{reply to}}.
