You may have created your first workspace by visiting PBworks.com and creating an account and workspace at the same time.  Once you have an account and are able to sign in to My PBworks with your email address, there is no need to create a new account to create a new workspace.  Just sign in at the link below:

If you have not yet created a free educational edition PBworks account, you can do so here:

Then, click the link to create a new workspace:

Note:  While free educational edition spaces can be upgraded to Campus and Classroom Edition for K-12 use, there is no direct upgrade path from the free educational edition to our Business Edition.  Do not start in any educational edition if you're planning to use PBworks for your business, as there is no benefit to doing so.  Instead, click here to sign up for a trial of our far more capable Business Edition.
