Multisite networks

Network-activate it and each site gets its own articles, FAQs, requests and settings — nothing is shared. Sites added later are set up automatically, and a site deleted from the network takes its requests and their attachments with it. A site deleted while the plugin was switched on for that site alone leaves its table behind at the time, and deleting the plugin clears those leftovers away. Each site chooses for itself whether requests waiting on the customer resolve themselves, and runs that hourly task for itself.
