MeBeam comes just a simple website in its look, with a central box and some other buttons, but in reality it is a powerful collaboration tool that allows you to create video chat rooms for up to 16 people.

After you type a name into the box, it will automatically create a video conferencing room for up to 16 people.

You can then invite other people to join the room by giving them the room’s URL: all they’ll need is a web browser, Flash player, a webcam and a microphone.

The service is completely free to use, and can be used without any registration.

Twiddla is a free web-based whiteboarding software, but also a complete online collaboration solution for every team that needs to communicate in real-time over the internet by chatting, talking, co-browsing pages, and whiteboarding.

After you start a new meeting by clicking the button on the home page and setting it up deciding whether it’ll be a public or password protected meeting, you can invite as many people as you want by sharing the URL (and the related password if necessary) via email, IM, or phone, or simply by clicking “Invite People” and typing their email addresses in.

Now that your meeting has started and has people inside, you just have to choose what to do:

• You can co-browse any Internet page by typing its URL.

  

• You can draw and add shapes on the whiteboard, or even on the web page you are currently browsing, by using one of the drawing tools.

  

• You can annotate the screen and upload images.

  

• You can text-chat with everyone in the room, as well as engaging a voice chat with them by clicking on the red button “Join Audio”.

  

• You can take snapshots of the session, clearing the board, and exiting the meeting at anytime with a single click.

  

Obviously the tool is completely free, and you can start using it now by registering and logging in to the service.
