All workspaces which are not Basic (first and second column below) are Premium workspaces.  These are feature-rich workspaces which also have very high storage limits, some even unlimited.  The table below outlines which features are available in each edition. If you have a workspace you'd like to upgrade, click Upgrade in the upper right area of your workspace.  If you have not signed up for a workspace yet and would like to sign up for a Premium edition, visit plans.pbworks.com and we'll get you on your way.

*Attempting to put more than one hundred users in a single workspace will lead to frustration, as there are no tools to manage hundreds of users.  If you need a platform to collaborate with a large company, you should use our flagship product, Business Edition.
