OK - hopefully these tools will prevent a full out attack of the PM’s from Dilbert-ville…

Liquid Planner (currently in beta) - is the best new online PM tool I’ve seen. Many of the online PM tools focus around collaboration (as does this one) but come off more like a task-planner and calendar than a true PM tool (think, Zoho Planner). Liquid Planner has a nice GANTT chart and other “traditional” PM aspects on top of the great collaboration tools.
Cost: (free during beta) else, $25/mo per user - first user is free.

5pm Web - This is another good one; lots of customization options, a great file/document repository feature, and easy to use. Also includes GANTT + collaboration.
Cost: $14/mo for up to 5 users and 10 projects (a great price!)

Project 2 Manage - More of a team organizaer and task list, but it is pretty well done and also…
Cost: Free

Task-a-Do - This is more of a collaborative writing PM tool. It tracks who edited and contributed, and where the document is in the pipeline. If you write a lot of proposals or other group writing projects - take a look at this one. It is very simplistic but gets the job done.
Cost: Free
