Conclusion

This tutorial provides the basics of creating a module that creates a new node type. Futher enhancements to this module could include adding Ajax-y goodness to help with task assignments.

Other enhancements could include adding additional fields such as a dependency list of other nodes (perhaps as a textfield, inputting node ids as a comma separated list) or an assigned-to field (assigning the task to a different user), or making the due date input configurable to the user's desired date input format (mm/dd/yyyy, for example).
