When a user registers on KDE Identity, they get a confirmation email. Clicking the link in the confirmation email takes to a form asking for more information, and when that form is submitted, the account is created.

This final submission takes long to complete due to LDAP problems, and sometimes times out. Often users then click the confirmation link again, which doesn't work because the account is already created, and then they email us to say they couldn't register.

Obviously the right fix is to make the account creation not take so long. But I think an interim improvement could be to send another email when the account is successfully created. Hopefully users will see it either before trying the confirmation link again, or before emailing support. In addition, including their username in the email may avoid "I forgot my username" support emails, which we also get somewhat frequently.
