You can download additional gestures from the Web (just use the ones on this web site or from the links that take you to the best sites). The Gestures you download must be saved in the gestures directory in order to be able to use them (standard: C:\Program Files\VPlaces\Exts\Gestures) but you can change the directory in VP:
Choose 'Tools' from the menu, then preferences, click on directories information. There type in the path for the gestures.
Now press the smiley on the chat screen and the gesture palette of the directory will be loaded. This is useful if you have many gestures.
