Probably a zillion possible ways... Maybe simply configuring a link or linkable object to the other site placed in one of the panes and configured to be viewable on all pages?

Thanks for your input gents. Currently my asp:Menu control links to an XML file that contains the structure for both sites. I use XPath to choose which sub-tree gets loaded. I was trying to think of how I could replicate this in DNN but I'm beginning to think this may not be a good idea. It may be better to set up each site as a child portal and try to detect a person's "Everyone" group and redirect when the parent loads. I'm a DNN newbie so if anyone knows a better way of doing this in DNN could you let me know?

Cheers

Mike
