Not much tough though, I would rather say a lot of understandable guidelines and instructions for every newbie threads are pinned at the top of each board by forum staffs and many og's which will help newcomers to learn and navigate forums barriers without any barriers. Goodluck!
The guidelines are always pinned there, but some newbies don't always know about it, which is why they are being pointed or directed to it each time they create an awareness thread about being new here, and sometimes they get more exposure with the kind of detailed explanation that they will get from other members who understand the rules very well, but some newbies, after this, don't make out time to read through all the responses that have been given.
Newbies are always novices and as such would make some mistakes but it is our duty or out of kindness to guide and direct them whenever we notice it or they request help just as this OP has done. I remember when I was a newbie, I saw the pinned posts on threads but I was afraid of clicking on them because I thought it would get me into trouble as they were pinned there by the admins so I avoided it not until I started reading posts and comments and I began to explore the platform and saw posts about the pinned post that was when I was courageous to start opening them and I read them all through and got more knowledge about the threads and the platform as a whole. Maybe this might be the situation of some newbies here and not until they are told to do so, they would not, or out of courage and boldness, they try to see for themselves what is written there only then would they have an idea what is written in the pinned post.
