I don't know if this is a part of the trial, but i was asked one question by someone then i believe i was kicked from the server? I'm not sure how this works.
Reading the thread should have answered your question, but I can explain it for you!
When you enter the server, you'll be given an unconfirmed role and a Helper should ask if you're ready to be private messaged.
Once you reply confirming that you're ready and prepared to answer the given question, they'll private message you on Discord.
If you answered it correctly, your unconfirmed role will be removed and you'll officially be welcomed as an EN applicant.
If you answered incorrectly, you'll be banned from the server and
will have to apply the 1st of the next even month, which will be October 1st.
