Hello there, Antonio! Lovely to see you here! <3
I understand you're confused and all but there's no need to worry! The members here are quite polite, and understanding, so if you have a question, we're all happy to answer them!
There's a lot of tools for you get help from, as well as great staff to come up to. Cirno, the moderator above me, specializes in newcoming members like you, so any questions like posting, the rules, etc, you should defo come up to her. :) She also linked you to some resources to get help from, so do take advantage on that. :)
I hope you do have a great time! See you around and good luck :D
