With OSI Affiliate software, you can set up to require affiliate approval before they get into their dashboard. In order to do this, follow these simple steps.

Step 1. From your Admin control panel click Set Up Software and then Settings.

Step 2. On the Settings Page, you will see different options with one saying Require User Approval click to Check that option. 

Step 3. Again Go to your admin control panel and click on Users and then Manage User, to check if the settings are working fine. 

Here you can see an affiliate required approval to get into her dashboard.  

So you can simply click the user edit button to see her details and at Status Disable you can click it as Active.
