Task/quest/project manager

[Kiint]

I'm after a module which would do some kind of multiple stage task management. Basically something like the following:

A user would be able to open a new task/project, give it a title and create many different stages, for instance:

1. project design
2. project programming
3. project testing
4. project beta
5. project release

or in a game situation:

1. collect 20 items off a named creature
2. hand in these items to xxxxx
3. collect your reward from xxxx

now each of these tasks would be able to be flagged with something like "in progress", "complete", "need additional help" or any other admin defined title.

Admins would be able to give the main task a priority, something like "urgent", "high priority", "low priority" etc, or anything else that the admin enters in the control panel.

Each of the tasks in each project would have an option where users with the correct permissions (from their usergroup) would be able to volunteer to help, or be assigned by the admin to help. And users would be able to add a comment to each stage of the task, maybe some extra info or a time when they are available to help.

The main window would show a list or categories which are admin defined, showing the last 10 (or whatever) tasks that have had work done to them either sorted by "priority", or by "last active".

When a task has all of its stages completed it can be closed (either by the author or an admin) and added to the library of completed tasks where any other user can request to use this task again but without all the extra comments from the original.

Is there anything out there like this?

It is the multi-stage aspect of this which I want. I've seen the demo of vB's project tools but this doesn't seem to have these capabilities, seems that you can only add one task/stage and that's it......easier to use a pen and paper for that, and I need something where you can customise all the names and words within.

Any info is appreciated.
