I have some advice for all new members. Those who are new make many kinds of mistakes in the forum. Those who usually make mistakes do not have much knowledge about the rules of the forum. So I will tell the newcomers to enter the forum and read the rules carefully.
Low quality posting: There are many people who post in forums but they do not post relevant topics, it is a kind of injustice. So everyone will try to give relevant answers to the topic. Otherwise the admins will be forced to punish you.
Can't copy-paste: Newcomers usually copy and paste more. So don't copy someone's post or text from any website. Copying and posting is a big injustice. If someone regularly copies and pastes and gets caught, you can get a much bigger penalty.
What I would suggest on the copy-paste issue is to go a step further and actually turn that type of posting into a helpful activity that can get you merits. Find a decent post that you feel is of good quality and translate it to your native language on your local board. Articles like those exist on the forum and some of them already have translations, so don't be shy and try it out. It takes some elbow grease, but it's worth it in the end.
