Lolita - No need for apology, we all have things to learn.
Just below the sign in area you will see a text that says "New Topic" that will take you to the new topic window. I am not sure how you can move your reply other that copy/paste.
Hijacking is when a person goes off of the original thread content/subject matter. In this example, the original thread was on the origin/source of a particular fig, Black Madeira, and your question had nothing to do with that topic. You do yourself a disservice when you do this as a lot of people may not open the Black Madeira thread that would open your thread if they had interest in your topic.
Please do not take this as a personal attack, only clarifying a forum process/procedure/etiquette.
