Actually I know that anyone who is new to any platform for the first time is considered as a novice or newbie but it is expected that anyone who is using a platform should be able to read/write and understand but it should be noted that every platforms have either their terms of service otherwise terms and conditions or rules and regulations that guides the activities of that platform and in the forum here we have the forum rules and the forum comprises of individuals with great intellectual capacities but it's still very odd to me how some people while making posts they will be using this statement "I don't know if anyone have talked about this or have created this topic before"
This is just a normal statement that people use to start creating threads on the forum. And I think they have their own reason because many people using this know that there is no topic that they will bring and will be new to the forum members. Many topics that we are discussing on the forum have been here before, but since we are newcomers, that is why they put that in their sentences because they know the topic is already here, so I think it is not bad. However, it is not only for newbies; sometimes we that have been here also use it when we want to reply to threads.
