[Forums] Return values from Popups

Hello. The EventSystem does not work that way with popups.

The notify from popups is actually a javascript message being sent from one web page (which is the popup page inside an iframe) to another web page (which is the actual page in the web browser). This message has to be sent through javascript, because there's no way to send messages from one web page to another on the server side.

The best way to go for popups, unfortunately, is to have type convertions from text to the type you need.
