Durn it. My hosting service does not support cPanel. How difficult would this be to develop? Well clearly you've already developed it you've just locked it away for some reason. Why not make a brand new paid Add On - call it User Data SOS? Really for the money you charge, it should be possible to export user data info freely. I for one, wouldn't pay to retrieve what is my own property - my user database.
I'm actively looking at alternatives to wpForo. Any suggestions?
