Baik makasih umpan baliknya om Husna, udah belajar beberapa kali dari trit itu tapi masih agak kurang paham dengan cara di trit tsb jadi saya menggunakan alternatif tutorial yang lebih mudah walaupun bahasa inggris sih tapi sayanya aja masih teledor mengikuti step by stepnya agan @o_e_l_e_o
Find the post you want to quote, and click on its title to reload the page to that specific post. Then copy the message number (last 8 digits) from the URL.
Then, in the thread you want to reply in, click on "quote" on any post. In the URL bar on the new page, paste over the 8 digits after "quote=" with your new 8 digits. Press enter.
To ensure the quote links properly, you then need to take the 7 digits after "topic=" from the original post (as in step 1), and paste them over the digits after "link=topic=" in the body of your reply.
Edit: reformatted and added in final step. Thanks to shahzadafzal and my dream2021.
