In Drupal, our website is set up so that people must validate their accounts when they sign up for one. Normally, they are not able to access the "subscribe" page (for specific training content that they pay for) until they have a validated account, but some people seem to be paying for a membership without validating their account first, which gives them all kinds of problems do to how content access is set up.
Is there a way to validate an account in Drupal at the same time that the member role is assigned to them?
