PBWiki, the wiki editor tool for groups and communities, has released a few new features, as requested by its user base.
Among the new features added include a spreadsheet, which is a live collaborative tool for users, voice chat, which enables you to leave a message for others that are viewing your wiki, and a shared calendar for scheduling purposes. Teaming up with Fliqz, PBWiki is also offering the ability to upload videos for free, presumably using the Fliqz widget, and PBWiki has also added another plug-in for planning events and selling tickets.
