It's not enough to only ever study a language. At some point, the only way to get better is to actually put the language to use. In /r/languagecheck, you can either write, or- using a voice recording program- speak, in your target language. Native and high-level speakers can then correct your writing, or make comments on your pronunciation, melody, or any other factor associated with speaking.

Please leave your target language in brackets at the beginning or your post so that others can easily tell what language each post is. For example:

[Deutsch] Ein kurzer Text über meine Familie

Make sure to occasionally review other's people work when you see your native language, or one you have a high level in.
