If you’re still on a PBwiki 1.0 wiki, you’ve probably received an email recently about updating to PBwiki 2.0. Beginning on March 9th, 2009, all 1.0 wikis will automatically update to 2.0.
Don’t worry — you have plenty of time to make the change (a free update, which takes less than 5 minutes), plus we’ve got an excellent support team waiting to help you.
When we launched PBwiki in 2005, we designed our system to be easy to edit and share. Now, 4 years later, our users have taught us a lot. You’ve told us that you want more control over users, more powerful editing/sharing features, and an improved user interface.
In 2008, we rolled out PBwiki 2.0 to address those needs. A year later, we’ve concluded that for just about every usage, PBwiki 2.0 works better than 1.0 for collaborating and sharing information. 2.0 even gives you new features like Classroom Accounts (which allow educators to invite students without email addresses) and Document Management.
Updating to 2.0 does mean learning a different user interface, but the folks who’ve made the switch will tell you it’s worth it:
Finally upgraded my pbwiki site to 2.0. why did i wait so long to do this! wow! – starryhope01
I have used PBwiki for 2 graduate courses with the same students. All of us like the PBwiki 2.0 over the earlier version. This version feels more intuitive and allows me to break the class into groups with their own work areas (folders). -Jane Allgood, Ph.D.
You can use a simple wizard to update to 2.0 (again, it’s free and takes about 5 minutes). You will not lose any content by updating to 2.0, and with Classroom Accounts (which replace invite keys), reader comments, folders, easier editing, full CSS customization, and so on, PBwiki 2.0 allows you to do just pretty much everything you could with PBwiki 1.0 and more.

You can update to 2.0 at any time, or you can wait until March 9th, and we’ll update for you.
To update to PBwiki 2.0, go to WIKINAME.pbworks.com/migration.php (just replace WIKINAME with the name of your wiki) and follow the instructions on screen!
