OK - fixed...it was not a permissions problem. I did not have "display in node list" checked off because I thought that meant all users would see it, not realizing that if the permissions were correct, that would not happen. Then I created a registered user to test it out and all is well. I noticed that the registered user default permissions have the view node not selected by default, so when I created a registered user, I couldn't see any of the forums I created. Once I selected View Node, all was ok. Is this correct? The registered user should have View and View node slected?
Thanks for your help!
