Last month we announced a groundbreaking set of new features available in our Real Time Collaboration update.Throughout the next two weeks, these features will be activated on all networks.
With these features all users, including network and guest accounts, will be able to:
- Chat in real time– With PBworks IM, you can chat from a workspace or network.
- Broadcast live, streaming edits– Editors can share real-time page changes to other users on the workspace.
- View activity updates in your workspace– Receive immediate notification of changes to starred pages and activity from the network users you follow.

Thanks for info and question: Do you intend to make multilanguages on site?
Chat in real time – good idea and helpfull, this is it what I needed
This is going to be great! My students who chat via comments will have expanded communication with this feature. One thing: please, allow students to have pictures or avatars for their student I.D. This change would be a great asset for communication and lots of fun for the kids.
Hi Rita,
This feature is only available for our Business Edition – not our Education Editions. There are plugin options for chat, like meebo and chattango. You can find more information on that here: http://educators.pbworks.com/Plugin
