I just visited the virtual reality community sMeet, which I may recommend. Visiting this virtual world is most easy as no software needs to be installed. I just logged in and the avatar chat startet within the browser.
There are also some outstanding features. At first there are the opportunities, which are most common to virtual worlds like chat, personalized avatars and rooms. One further feature at sMeet is the ability to contact other members by phone to talk with each other. Doing phone calls is not expensive and to try this service every new member gets some free coins. People do make phone calls anonymously by call back. The best feature to all video fans probably is a showroom function. By an internal menu people are able to fetch videos from other internet services and to watch these videos synchronously. So if you like a break, visit sMeet.
