Unfortunately the Quick Register mod doesn't redirect the user either after registration. It just drops you to this page:
Thank you, newuser. Your registration is now complete.
You may now proceed to edit your Profile in order to fill in additional personal details about yourself, or you could modify your Options to customize your browsing experience of this site. If you would rather do these things later, you can do so by following the links around the site to your User Control Panel.
Alternatively, you can simply go back to the Forums and start posting in threads.
Any ideas on how to get it so that the user is redirected to where they wanted to go?
