1. Text Chat

1) Send Message

The message will appear in the chat lobby if you simply click Send when you're done with inputting, but if you need it to be received only by a specific user, double-click the user in the userlist and a private chat window will pop up. Or left-click a username and choose "private chat" in the user panel.

In the same panel you may find a down arrow, click it to get "personal message" and "whisper". What's the difference of them with the "private chat"?

Personal message will appear in the chat lobby like this: "a > b: blabla." and everyone can see. Whisper, on the other hand, will appear in the chat lobby as well but like this: "a > b:(Whisper) blabla." which means only a and b will be able to read it.

2) Hand-written Message

In 123 Flash Chat, users may create and view handwritten messages, whether in chat lobby or in private chat. A message can be more creative and powerful in this way.

The Handwriting Mode can be activated by clicking the Handwriting Mode in the Writing Mode down-list above the input area.

The pen size, color can be defined here, an eraser is available to erase a specific stroke. The other two buttons are undo and redo. 

Currently the handwritten message won't be recorded in the message history log yet.

Additionally, the text input field becomes resizable, whether in text input or handwriting mode, to the maximum height of half of the chat itself.
