In my opinion a new topic should be introduced in bitcointalk in 2023, I think this topic should be about that :
1. Where to start the newbie ID.
2. Full use of post reply box.
3. Guide line for posting pictures.
Etc etc....
That won't be necessary as everything you need to kickstart your journey on the forum has already been prepared by previous members. For example, with a quick search on or off the forum, newbies can easily find thread that beautifully explains how to do whatever they want to do on the forum. For the question you highlighted here are some threads for that.
Where to start the newbie ID. I believe you meant, Where to find the newbie ID.

And when they search and don't find answers to their questions, they can just ask then lock thread immediately they get the response that's helpful to them. Unless newbies by default will be redirected to the thread that you're suggesting when they register, it might be effective as you think.
