Proper Netiquette
Because many people are jumping into these technologies, such as web forums, without understanding many of the basic areas of etiquette on the internet. I think that it is now time for me to go ahead and give you all a link which I outright demand you all read. You need to know proper Netiquette!
Of course, I know many of you are very good about netiquette, and let me say how much I greatly appreciate this. For those of you who may never have had this type of education, it is about time that you do! It really does make the internet a more pleasant place.
