I am having people join and then they need to upgrade membership right away. This is causing a problem because people are having a hard time finding the the place to sign up for the upgrade. I want to make this as easy as possible for them. Sending them to a purchase link for the upgrade is not working either because it says that username is already taken is there a way to send them a link to click on that will be like using the add subscription feature. So I just want them to click on a link and come up to a buy page for the exact product I want them to upgrade to. Let me know. Thanks
