Just last week, we rolled out major improvements to how you can work with files in PBworks to our business customers. We’ve gotten such a good reaction to these improvements that we’ve decided to make them available to everyone, including free users.
Starting with Release #520, everyone will be able to tag and comment on files, while premium users on Classroom and Campus Edition will be able to set file-level access permissions, just as they’ve been able to do with wiki pages and folders.
You can read up on all the details here.
