Because this forum is the most active discussion space for many of the things raised, I want to say make good use of every discussion. There is no need to write or express something that is beyond our ability to make it appear to others that we are great while what is conveyed is misleading or substantially wrong.
Well show off doesnt necessary when you are engaging in such discussion. Maybe some tried to set off but anyone would feel that he is just boasting over what he knows and or course thats not a good trait. Maybe share what you only understand and dont be so confident cause others might have also idea that you are just showing off right. Some newbies tend to do that of course they are after the merits so they try everything even this.
