A signature can be set by each personnel to be included in each message. The signature will be of up to 255 characters (2 characters are left spare for the line break between message and signature). A typical signature may include your name, phone number and a canned message but it is totally customizable according to your needs.
To create a new signature or edit an existing one, click the Settings menu denoted by the icon at the top right corner of the Text Messaging Dashboard window and select the Edit Signature option. The Edit Signature option can be used to open the Signature window where you can edit your signature.
