Does anyone know what I may be doing wrong? I tried the method that Joe suggested but I doesn't return the logged in user.

Actually, that's not a dumb question at all. 

I checked and the cookie is being transferred over the wire. I tested this with Fiddler2 and verified it was the same cookie that is stored in the browser. 

Any other ideas? Anything helps. :-)

I think you may be on to something there, Richard. I haven't had time to play with it, but the theory goes like this. DNN is a single aspx page, Default.aspx. Somehow it can leverage the DNN Framework, so I'm sure within there lies the code that will help me. Maybe it is something like System.Web.Security.MembershipUser.GetUser. All of this is beyond me. I wonder if assistance in this area is covered by DNN Professional support?
