New Member Registration - Email address is not being stored in the database

@Tiaan - My original plan was to manually create my clients in the database so I could send them a “Next Steps” email and attempt to control the password they used so that I could log in to their account from time to time to ensure the dynamic pages were functioning properly. The problem I encountered doing things that way is that, in short, it doesn’t work. Despite there being an existing email address on the database, the system created a new member. Therefore, I was forced to turn the auto-approve off and set up a triggered “Next Steps” email that would be sent to the client after they were “approved” as a member. Do you think the source of the problem is that my site is not currently set to auto-approve members?
