Thanks for the hint.
In OpenACS I can rename an 'instance' but to change the url I have to unmount the instance, delete the node, recreate the node under new name, then mount the instance under new name.
For dotLRN, I changed the 'package_key' proc in dotlrn-procs.tcl and then selected 'Applications' in 'Main Site Administration' and changed the 'url' parameter for the dotLRN application.
I don't know how to change the 'clubs' url part but I think I will have to do that in code.
Any assistance appreciated.
