JDE Expense management module

Where is the JDE Expense management Community? 

Is there anyone on this post that uses the JDE expense management module?  And if so, will you send me a diagram of your current expense report workflow routing rules and setup as well as departmental procedures?  We have used EM since 2006.  However, because we were forced to custom code our procedures into the JDE EM module, we could not apply ESU's, etc.  We now are using EM 9.0, and would like to go back to "JDE out-of-the-box" EM setup so we can apply ESU's and updates.

We are trying to redesign our workflows as well as our group profiles.  Any information that will help us get setup would be greatly appreciated.  We have the Oracle JDE documentation but we want to know what other organizations are doing to work around
