The steps you observed before making a post are the right ones to do.
I want to add one more point, namely use the search section to find topics or threads that match what you want so that the same discussion doesn't happen.
No need to create a new topic if a topic with the same purpose already exists. Just reactivate the discussion.
I don't think it is bad to make another topic out of it, because even if the topic has been shared by many other members by different titles and contexts but every time each member comes up with a different and unique thing and to be honest, I don't think it is easy for a newbie to keep track of all the past topic created on the same topic.
And why a warning is given on a topic to which there are not one has replied for the past 120 days? I mean that's an open indicator for those, to not post something in them but creating another topic on the same thing with different post content is okay. Don't you think, Just a curious thought, not implying anything?
Here is another source from 1miau about how one can improve their post quality. For local board and global board also (I guess).
All newbies should read this, in order to be a quality poster and to improve their writtings.

Thanks for adding this useful source, it will be helpful for those who were not aware of such rules like me. Are we sharing the threads here that would help others, as the OP wrote the title in a way that "My little drop" like he is contributing from his side? Well, whatever, I will also add useful threads that I have kept track of. These threads will help all of the newbies and ranked members of this forum.
To be honest, at the start for a newbie, things are difficult here, especially for those who are non-technical and have no IT mindset because they will be stuck in the HTML tags used to write in the text field.
