I am using Membership2 plugin, which is such a nice plugin, so easy and flexible. But my business is small so at this stage we only have one level, agent - free. Since we implement user approval registration process, we already sent out the user approval email, and one accepted as our user, becomes agent automatically. Therefore, we do need to send out membership approval email. It is redundant. Please help me not sending out this auto emails after I change their membership level to "Agent".
