Try not to yell, this is where you either type in all capitals or use text editing to increase the font size and bold type of your message.
In IRC's you can only type in all capitals, there is no text editing.
You can use as many asterixes as you want when typing these out. From hugging an on-line friend to giving someone a cyber-beer to drink.
Also you can use the abbreviations previously mentioned also.
But don't let this stop you from keeping in contact of each other.It is another way of getting another chatter to talk to you, but it is considered to be rude unless you have no choice to, which is usually when no matter what you have said in the chat, everyone is still ignoring you even though you have not typed anything rude or insulting.Chat Abbreviations To cut down time on typing, many people have started using abbreviations for various actions and phrases.With IRC chats however just type in the addresses for the person to write down since IRC's are text only and you cannot go from an IRC chat room directly to the world wide web. And after talking with this person for some time you may become attracted to them and vice versa.It just might be what we call in cyberspace, cyber-love.
For a much bigger list the WBS Chat Book has a whole list compiled from various users from all over including various smileys!! If you choose you can use text editing to increase the size of your text to catch someone's attention.
