Vocabulary learning

Memrise is one of the most versatile sites for providing pre-made mnemonics for vocabulary in a wide range of languages, which is always expanding since the system is open to people adding their own public vocabulary lists and suggestions in.

Ankiweb - while this works best as a smartphone app or program, there is also an online version you can use, and you can input pre-made decks of the most important words in that language from a huge database. 

Quizlet is another flashcard based site with lots of language specific ones.

Get it pronounced

Forvo is a great site if you come across a new word and would really like to hear how it’s pronounced by a native speaker. It has a huge database covering many languages that you can search and get an instant answer.

Rhinospike is better to hear how an entire sentence or even a couple of short paragraphs are pronounced by a native speaker. Submit your request and make sure to help fill those requests in your native language to have yours prioritized.

Lang 8 is a site where you can write text in a particular language, and pretty soon have natives look over it and give you great feedback. Highly recommended for improving your writing skills!
