Hi. We've got a guide covering the process over here: http://software.informer.com/partners.php. It's written with Software Informer in mind, but everything is done the same way on Mac Informer. The whole submission process basically boils down to the following two steps:
1. Install the Mac Informer client app on the same computer as your own program.
2. Click Refresh in Mac Informer - the program will send the new title to our database, and it will automatically get an entry of its own.
