This action is meant as a module for the UserAdmin tool.
To use it as a standalone action simply add: {{usercomments user="UserName"}} in the page body.
 



This action displays a list of pages commented by the current user or by any other registered user specified either via a user action parameter of via a user GET variable . If no user is specified and the current user is logged in it displays a list of comments by the current user.

Save the code below as actions/usercomments.php.

Current version: 0.4

/**
 * Display a list of recent comments posted by a user.
 *
 * This action can be used to display a list of comments posted by a specific user. It
 * accepts a user value both as an action parameter and as a GET parameter. The
 * specified user must be an existing user. If no user parameter is specified
 * or the specified user is invalid, an error message is printed. If no user parameter
 * is specified or the specified user is invalid, and the current user is logged in,
 * the action will display a list of comments recently posted by the current user.
