To sign a message, move the cursor to the end of the message, and then with your mouse click on the sig icon ( or ) in the toolbar at the top of the edit box. This inserts the signature code (~~~~) where the cursor is. When you save the page, these tilde characters are converted to your signature followed by a date stamp.
You can also type this code in manually with the four tilde characters ~+~+~+~.
- To sign without a date stamp, use three tildes ~~~ ~+~+~ instead.
- To sign only the date stamp, use five tildes ~~~~~ ~+~+~+~+~.
