Thread:Feedback/Editing posts

I have edited directly Thread:Talk:Sandbox10/Test_(2), but there is no information that it was modified by other user.

Update: I accidentally deleted that page. The new example is on Thread:Talk:Sandbox2/Editing someone's messages‎.

Edit was performed using API, request: {         'starttimestamp' => '2009-10-01T15:10:52Z', 'bot' => 1, 'format' => 'php', 'summary' => 'Lorem ipsum dolor sit amet', 'text' => 'Even more evil comment!!', 'action' => 'edit', 'title' => 'Thread:Talk:Sandbox2/Editing someone\'s messages', 'token' => *CUT* };
