Powerful Collaboration Features
Collaborative Page Editing
Let multiple people collaborate on the same page. No need to send documents around and wait for comments -- your pages and documents can be centralized on the wiki for as many editors as you grant access to.
Document management & file sharing
Use PBwiki's Document Management feature to share documents, spreadsheets, Powerpoints, or any kind of document imaginable -- right on your wiki.
Complete history and audit trail
PBwiki keeps a complete audit trail of every change made to your wiki. See who changed what. Reverse any change with a couple clicks. Your PBwiki allows you to maintain full accountability of your users.
Easily invite others to collaborate
Invite 1 or 1,000 users to your PBwiki in seconds. (If you're a teacher, PBwiki also features Classroom Accounts for students without email addresses.) No more complicated user provisioning and no more waiting for IT. Inviting users is easy.
Users with appropriate permissions can leave comments on your wiki pages. PBwiki sends comment notifications by email/RSS.
Automatic notifications by RSS and email
PBwiki notifies you of every edit so you can monitor changes and engage when you need to. Notifications by RSS and email allow you to keep up to date, automatically.
Security
Access Controls
Control the access level of your users. PBwiki includes robust access levels (Reader, Writer, Editor, and Administrator) for differentiating access to your wiki..
Page and Folder-Level Access
In addition to controlling wiki-wide access levels, control which specific pages users can access. Your marketing team can be restricted to pages in the Marketing folder, while your CEO could see all pages. Page-level access is perfect for sharing specific pages with third-party consultants.
IP whitelisting and blacklisting
For additional security, you may grant access to specific IP addresses to guarantee you know who's accessing your wiki. IP blacklisting, on the other hand, allows you to blacklist specific IP addresses (perfect for banning users from your wiki). This feature is only available on business wikis.
Easy to Use
60 second setup
Why wait for IT or your web designer to set up a collaborative site for you? Create a PBwiki in less than a minute -- no technical skills required. It's as easy to make as a peanut butter sandwich.
