How can I install optional modules for PostNuke for single websites only on a server with more than one PostNuke portal. When PostNuke is installed, it is (optionally) available for all websites, via the domainname.com/PostNuke URL. A seperate database is created for each domain as needed. However, the PN files are located in the /var directory on the server. Strangely, a PostNuke directory is added to the /home/user/domainname.com/ directory; PN appears to ignore this for some reason. I can't quite figure it all out. Any ideas?
