I don't need a fix on my site for this (as I've temporarily done a code fix), but just letting you know....

The 'Drop Down Menu' module still shows the 'Forgot Username?' link even when the site is set to use email as the username.

Other areas of EasySocial, for example the menu bar and the main login area, are clever enough to hide this 'forgot username' link if it isn't needed.... looks like the drop down module should do the same.
