Userplane’s webchat is flash-based, unlike the Java-based ParaChat. It not only has text, but audio and video as well. There aren’t ads, but it says that it’s provided by Userplane. Ordinary users can create rooms, though they can delete only the ones the created. There’s a little bit of admin control, mainly just kicking and banning. Take a look, you may like it. Userplane was purchased by AOL a year ago, but they’re still providing their services as they were before.
