This plugin was originally written for a client, but may be useful for others. The client was using the s2Member framework to manage paid users, and WP Affiliate Manager to allow members to make affiliate income. They wanted members to get an affiliate account automatically when they registered.
When a user registers on a site using the s2Member framework, this plugin automatically creates an affiliate account for the user.
Errors and successes are logged in the WP Affiliate Manager log files if debugging is enabled in WP Affiliate Manager.
The plugin is available from the WordPress plugin directory, or you can search for “Auto s2Member Affiliate” in the WordPress plugins screen.
