I do not know who “we” is so I am going to assume that it is like the general “you” in the initial post, a general “we”. To that end, I am just addressing you.
You are correct that your unfamiliarity stems from your newness, not from your age, and please do not let anyone convince you otherwise; youth is bright and held in good regard here.
Do not worry though, this type of unfamiliarity is not a new thing to the Forum, which is why I made a suggestion not too many months ago (note again that there is zero age component there). While it is still under discussion, I think @jasonhernandez74 made a really great point in his post.
In case you did just that, here is a link to the Guidelines. (Also handily you can tab at the top to FAQ, About, TOS, Privacy.)
I think reading those is the best way to start remedying your unfamiliarity, followed by just reading around the Forum.
PD: To be clear @naturespotter, I had not particularly noted your newness/unfamiliarity or would not have commented on it. I only do so because you brought it up! I could not say if it is or is not noticeable to anyone else. (I have been more absent than usual and distracted when here recently due to a move.) In any event, welcome if I did not say say so before.
