Backpack,the personal organization tool from 37 Signals, got a lot less, well, personal today. They have rolled out a new multiuser version that makes it easier for small teams to organize and exchange information. As stated on their product blog “Backpack brings the promise of the intranet back and delivers real value by keeping things simple”. Indeed!

Amongst the new features are:

* Multiuser – The ability for multiple people to log into a single Backpack account.

* Calendar – The calendar gets multiuser aware as well with the ability for users to share a single calendar and selectively allow access to calendar items to certain people in your group.

* Newsroom – The new Newsroom tab gives you a birds eye view of all of the recent activity in Backpack. Very handy in a multiuser environment.

* Messages – The new Messages feature allows people to post messages to the group and allow for comments. Great for general announcements.

* Reminders – Now, reminders can be sent to many people as well as just yourself, via e-mail or as a text message to a cell phone.

If you have a small team and are looking for simple and straight forward way to collaborate, share task lists, share appointments, etc., Backpack is now a fantastic solution.
