After learning this plugin was not available for BuddyPress, I installed another instance of WordPress specifically for the use of the Directory Plugin. I'm now confounded by the fact that the plugin seems to insist of forcing payments .... and this is not my client's desire at this time.
Within the plugin, I can see there is a folder entitled payments in the modules. What code do I need to modify to make it NOT force payments? I tried a couple of things last week (before my computer crashed and distracted me) and they all seemed to result in fatal errors.
