Scribblar has immediately joined other applications on The Best Online Tools For Real-Time Collaboration list.

It allows you to create a virtual “room” in seconds — without having to register — where you can collaborate for writing or drawing, with the ability to have a text chatboard or audio/webcam communication.  It couldn’t be easier to use.  If, and when, we can ever coordinate time zones, it would be a neat tool to use for collaborating with others in the International Sister Classes Project.

Heather Voran contacted Scribblar after she read this post, and learned that there is no limit to users in a room, except what is practical in that type of meeting, and the url does last indefinitely, but you have to bookmark it because it is not retrievable from their website. Thanks, Heather!
