One of my players knows of Roll20 only through the player link to my campaign. And he has forgotten his password. Forced to abandon the browser that memorised his commendably secure password, he goes again to the URL for my campaign. Where he gets a log-in pop-up that has no "I have forgotten my password" link on it.
When he reports this to me I assume that he means that the "forgotten password" link (which does appear when I log in) is not working, because I am unaware of the difference between a GM logging in to app.roll20.net and a player logging in to <a href="http://app.roll20.net/join/666/gibberish" rel="nofollow">http://app.roll20.net/join/666/gibberish</a>
