ooVoo is a video and audio chat alternative to Skype. The software can be downloaded or used via the web. You can pay for premium features either by month or by use as well. ooVoo is a great option for one on one chat conversations. What is great about ooVoo is that you don't have to download the software to use it because you can just use the web-based software. You can also send files up to 5MB for free, or with a premium account allow the ability to share your desktop. I have not really had the ability to use any video conferencing software, but it can be very handy in education and serve multiple purposes. ooVoo claims to have better resolution and better audio, so for those of you that video conference this might be an alternative worth examining.
So what exactly do you get with the free service?
