My experience (thought limited) has been when I remove a member from the system, though they no longer exist, if they try to sign up under a new name with the same e-mail address, they receive an error message…e-mail address not available?
Is there a way to purge the system of these pieces of info so they can be reused? Is there a setting to allow for the use of one e-mail address across multiple user-names?
Thanks
