State Workflow

I am looking for assistance on creating a workflow template that would do the following:

If an EPM document is manually (outside the revision process) set to "in work" and stays at this state for more than 3 days, the workflow would send them an e-mail reminder to set back to released state. When the user gets the e-mail, the workflow would start over and give the user another 2 days before emailing again, this would continue until the item is back to released. This would jab the user to get the item back to released ASAP.

The revision process (we revise from release which creates a new version at in work) and new docs would not be subject to this process. We don't run into this often....be we do have new users that sometimes make mistakes and set cad docs to in work, then forgetting to clean up after themselves. I cannot lock this function down as we use family tables everywhere....BAD. We have a test server, so I can mess around as much as needed.

This will be my first workflow....so keep the answers to a Windchill 6 month old level.

Thanks in advance for any assistance.
