Prompted by this question
Are we going to have an option on the close menu to migrate questions to Super User (if appropriate)?
Now that a better "off topic" migration dialog has been implemented - Adapt close dialog UI for upcoming avalanche of StackExchange 2.0 graduates - when are the Super User and (possibly) Web Masters options going to be added to ours.
