Looking for project managment system (web based?)

[Phalanx]

There was a time when I attempt to do exactly what you are. Unfortunately our teams leadership was completely opposed any kind of structured, and being held accountable project plan.

There is an open source tool call Dot Project for Project Management.
http://www.dotproject.net/

It's easy to install, only requires PHP, and MYSQL. although you need to install it on your own server. If your team has its own web site it's likely you have the necessary components.

It's a web based interface for end users to manage their tasks as well as administration.

It has Gantt charts, email notifications for tasks behind schedule, it's a very powerful tool. Get it installed quickly, learn how to use it and administer it BEFORE build season arrives.

I highly recommend it.
