My understanding is that you need a user page link such as Jmorgan, which can be added with a template such as {{ping}}, but doesn't need to be. The trickier part is that the same edit that adds a user page link must also contain a timestamp in order to create an Echo notification. This is a hack to avoid false positives. --MZMcBride (talk) 06:06, 3 January 2016 (UTC)[reply]
