The format used to do it is like this: **your action here**.
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.
For example, to ask someone a question you may want to use this format to do it and to talk to others the same way: Person's name: Your question Most of the time you will get someone's attention this way.
Just keep in mind however that things can happen in a chat just as they do outside. Just as the name implies, cheating can happen on a computer just as in real life.
Chat Abbreviations To cut down time on typing, many people have started using abbreviations for various actions and phrases.
Many of the abbreviations used in chats have pretty much become universal and a lot have become creatively humorous thanks to many regulars in those chat rooms.
Also you can use the abbreviations previously mentioned also.
When in IRC chats there's the "/me" command to do your actions.
In IRC's you can only type in all capitals, there is no text editing.
