Both your Name and Icon can be changed in the Preferences section. For more information, see 'Preferences' under 'Getting Started'.
Your Name: The name displayed next to your icon will be the name that is listed on everyone else's contact list. For example, if next to your icon, the name John is displayed, everyone will see you as John on their list.
Your Icon: A large collection of icons have been included with Tonic so that you can add a little personality to your online presence.
Icons can be added to the collection by copying windows icon files to the Images\ directory of Tonic. Once you select the new image in the Tonic Image Tab (under preferences), your image will automatically be sent to everyone else on the network.
