Nivi's launched Slawesome, a voice email service. I just signed up, so I'll try it out and report back. Check it out here. One review from Solution Watch:
"Slawesome is a really… awesome service that actually lets you record your voice without the need of software and send it to someone so they can hear you for free. You are given the spotlight for two minutes as you record yourself using a simple mic and Macromedia Flash. Registration is free and easy. You get an inbox, outbox, the ability to make your messages private or available for the public to hear, and you can send it to anyone that has an email address!"
