<human>: Could you distill the essence of the text into 1-3 sentences?

So I am an American high school student that just went on summer vacation. I took a German class for two semesters and really liked it. I wanted to join a subreddit that had a lot of German speakers on it, for tips about how to improve my German as well as how to see how native/fluent speakers use it. I looked up the subreddit r/german and it was blocked by its mods to approved submitters. I looked for alternatives, but that is the only german subreddit that I was able to find. So my question is, how do I get invited to join this subreddit?
<bot>: I want to join r/german to increase my german skills, its blocked to approved submitters, any advice on how to join would be appreciated.
