No, not the fruit. Mango is a new (still in Beta) online language program that allows you to learn 9 foreign languages using a Flash-based website. There are also two English programs, one for Spanish speakers and one for Polish speakers. Since the program is still in Beta, there may be a few bugs, but I didn't find any. The program uses lessons and slides so you can skip around to any slide within the lessons if you wish to repeat something or skip ahead.
