What do you use to brush up on your second (third) languages?  Chatterbug is an online language learning platform that offers interactive and engaging methods to learn languages like English, German, French, and Spanish (https://app.chatterbug.com/signup/).  Have you used it? Alternatively, you could try https://www.lingq.com/. With LingQ, you choose a language, then pick out topics with which you’re interested. You can both *read* and also *listen* (in loop format, if you like) to sentences in the target language, breaking them down by phrase or by word. You can even import your own material and ask LingQ to help you study it. It’s actually kind of awesome. (Thanks Joe and Eric!) But — what tools or platforms do you use for language learning?  Please comment!
