There is say that if you want to go fast follow the foot steps of successful people, this is also implies in the forum. To be successful in forum look to those in higher ranks that is when you will progress. The higher rank members did what is takes to achieve it to that position you found than now, if you follow their foot steps the sky will be you limit. The best thing is that stop looking at their various rank just focus on how to get there, but still dey should not be in rush to get there.
While they do that, they shouldn't plagiarized their posts or they'll end up losing access to the privileges of the forum. Looking at how quality higher ranked users are writing, is a good way to build yourself but also you have to be unique in your own way. Don't just copy everything they do, take the good things and work on improving them. When you add your own style and spices you get a pattern for yourself. One good thing to work on as a newbie is your writing style. The way you write also helps to communicate the thoughts you're writing. Some newbies ignore the use of punctuation marks and spacing (paragraphs) in their posts and this messes up everything they were saying in their replies.
Not taking the forum too seriously is something you can’t have many individuals do. It’s hard for users who have built their life around the forum not to take it seriously. It almost feels like there life, there second life and somewhere they can express themselves as well as find solution to solve some of their life’s problems.
Probably what he's trying to say is that we shouldn't get too emotional invested into the forum, what will happens tomorrow if the forum is no more. The forum is just another social community on the internet and all you're needed to do is to follow the rules that the forum has provided for her users to adhere to and you'll be in good hands. Communicate on the forum like you'll do on other platforms and don't put pressure on yourself. If your post are of quality, there's every tendency that it'll be merited. It doesn't matter if it happens now or takes longer but make sure you're enjoying the forum while you're making use of it. Some people take the forum too seriously that you begin to think if they don't have a life outside the forum. He's just trying to advice newbies not to be like those set of people.
