Save Lightroom Catalog .lrcat on network drive so others can edit

[pjbarbour_rotor]

I have a Lightroom Catalog that I want to put on a network drive so that my co-worker can work on it while I'm out. I tried moving the files and folders to the network drive from C:\Users\PJ\Pictures\Lightroom to a network drive. But it merely created shortcuts back to the C drive. Any ideas?

That's awesome but why not just use iSCSI since you are on a QNAP?  Or is this mainly for dealing with multiple editors to ensure access while catalogs are open do not cause corruption?

This is also a good reason for Adobe to prevent multiple users access to the same catalog.
