I also noticed that some high ranking memebers are fond of looking down on newbies and making them feel they are not good enough to make some types of contributions to the forum.
Not only on this board high ranking members make corrections in a harsh manner because that used to also happened on the main boards. This approach is consistent across platforms, and it's how we've been learning here. And I have to be honest, I've benefited from this method of correction. But the reason why it's common here is that, this is the typical method of making corrections in Nigeria. If you think back to your school days, you'll remember that some teachers were gentle in their corrections, while others were stricter. We have different kinds of individuals here with different methods of explanation, so newbies shouldn't take it personally if they've been corrected in harsh words. Instead, they should see it as part of the learning process.
