Answer 1

Answer:

Actually, both are ok depending on the context. If you'are speaking at the present moment about your past experience which affects your present day life, use “I've joined”. E.g., “ I've joined a chess club. It's really great!”

If you speak about your past experience after which something else has happened, use “I had joined”.

E.g., “ After I had joined my school chess club, I improved my skillss greatly. I entered a contest last month and guess what? Was ranked second in my group!”.
