VoIPnews.com has published this handy guide called Hacking Skype: 25 Tips to Improve Your Skype Experience.

These days, people freak out when they hear the "hacking" word. It is sometimes associated with criminals and breaking into stuff and stealing and god forbid what else. But the article actually uses it in its true original correct meaning which is simply to "expand" and "use in different ways". We indeed designed Skype to be simple yet expandable and versatile, and this article provides good testimony to that purpose. It lists many useful tips, from Skype's own features to many [extras](http://extras.skype.com) that we have.

I won't list all the tips here, [go to voipnews.com](http://www.voip-news.com/feature/hacking-skype-020607/) to read it all. I found this one the coolest. Many people have asked me for a Skype plugin that can distort your voice or mix music into the call. I didn't know we already have one.

> There's nothing more entertaining than changing your voice to mess with your friends. Whether you want to impersonate their boss or their girlfriend, [DoNaut](https://extras.skype.com/414/view) has got you covered. This easy to install Skype add-on will allow you to adjust the tone and quality of your voice throughout the call. In addition, you can use DoNaut to pipe in some background music to your Skype calls off your favorite music player such as iTunes, or Windows Media Player.
