Newbie here! Where should I write the comment requirement?

Thank you for all the useful information. I just recently signed up to join the community kingdom.

Hello @XiangLing, the simple answer to your question is that you write your comment in the blank box that is at the end of every discussion topic. Once you start writing the 'save draft' button changes into a 'reply' button.

Obviously please make sure you also follow the links provided by @kiara_wael
