Hi I've installed super orders but the instructions are telling me to
"6. Install "Purchase Order" Payment Module
The PO tracking system and attached reports won't work without this! Go
to Admin > Modules > Payment, you should find "Purchase Order" at the
bottom. It should look familiar when you install and configure it,
since it mimics the "Check/Money Order" module."
When I go to Admin>Modules>Payment there is NO "Purchase Order" module. Is this a non standard module that I need to download and install? If so can someone link me so I know I have the correct one. I currently use authorize.net so I've never really looked at the other payment modules before.
