Robin Good: Meetingl is a free video conferencing tool that allows you to meet, talk and chat with up to eight people without having to download, install or configure any software.
Fully browser-based Meetingl works across PCs, Macs and mobile devices, and it is as simple to use as it gets. To start a session you simply click on "New Room" and instantly you are placed in a uniquely numbered room where you can invite your guests. You can share the URL of the meeting room by clicking on the "room number" that will appear on the lower left part of your interface.
Free to use.
