IRC
IRC stands for Internet Relay Chat and it is a very useful software for any one into chatting online. This makes chatting easier and many people now use it for advertising and official business. That’s exactly what I plan to do as well.
As I mentioned my web hosting company idea in the past, I plan to have a channel for it on IRC and hopefully sell some space to people using IRC that may need it. And of course this will be a great way to give support online. Can’t beat that.
