Kingdom of Loathing- How to Write Messages

To write messages to other people you know in the Kingdom of Loathing, you first simply click the "messages" button, which is located here:

Hopefully you can see where the arrow is pointing. If you can't, it is on the bar (well, not exactly bar....) on the top of the screen that says stuff like "Character, Inventory, Skills, Quests..." and things like that. And then you click something like "Write" and you make a message. It's kind of like e-mail in a way.
