OOPM Tool for the Project

To collaborate over the internet on a project to develop a project management tool for an office suite is very difficult.

Many of the contributors are experienced project managers who are familiar with project management tool and not a community tool as CollabNet and it's IssueZilla.

IssueZilla has it pros which will be used when developing OOPM but to handle the process a project management tool is needed - and a webbased one - and in the spirit of the OpenOffice.org community an open source one.

Do you know any open source webbased project management tool then please list them beneath - thanks.

The decision on which of the suggested tool will used will be based on:

• the community around the tool - size and activity
• the way possibility to integrate with the future OOPM application
• views needed by the OOPM project (have you any suggestion for needed views)
• * Work Breakdown Structure (WBS)
• accessibility from major browsers and operation systems
• license to use
• possibility to get a free hosted service for OOPM Project
