(2009-06-04) Pbworks Project Version

PbWorks is moving its TeamWiki closer to Project Management Software. PBWorks uses the concept of milestones as a repository where you can see tasks, notes, links along with the conversations that are occurring within the task. Tasks can be rolled up into larger milestones and you can assign specific tasks that you can tie to workspace pages or leave as independent action items. (Task Hierarchy) Priced at $20 per user per month with no fee for guest/partner users.
