This does look quite strange because most users here who have done enough activity must already know the standard information like this. but it could be a reality because of lack of information and also no sense of desire that usually begins because it is less needed. so I suggest to some new users who are familiar with this forum it's good to learn from the beginning and open every post here. it can be a good start of knowledge and we can use for later in the future. a lot of information in this forum and if we have a desire then we will surely be able to get a variety of important knowledge.
