Hello @Subyss and welcome to the MLPTP! No, there's no "unspoken rules" but you can find the MLPTP Rules & Terms of Service here. You will also see that some of the forms have their own subsection rules pinned at the top as well.
But if you ever have any questions you can always message any of our Moderators or Admin. We are always happy to assist as best we can or find the right answers for our members.
