I dont understand how to use my logutech

the web cam should have a driver to allow it to communicate with the PC ....after the driver ( the CD from the seller ) was installed ..just plug the camera ...and let the PC find it ..and all
after is proper installed and all the things are OK ...the main use for it is to make video audio calls in MSN messenger ...or Yahoo messenger Skype ...etc
all you have to do is to click the camera button from the conversation window ...and the other person receives an info for your intention ...in that moment you already see yourself in a window
second ...you can use it to make capture like a picture or a/v movies ...using the AM cap feature from the start menu ...( all programs)
