Perhaps you misunderstood this part of the code. A click on the button
will popup the RSS url which the user has to enter into his rss reader.

done: public $task = "mail|login|logout";

done (IE does ... I have to check with firefox)

There are some special chars which are not handled correct this way.
But I will think about to simplify it.
