Hi friends, l want to be auto login after registration.
What can I do?
Thanks.
Is there any body that help me? 
Seeing as the self registration is based on email verification, I don't see how this would be possible. Perhaps you could hack the code so that the email verification link also logs them in but that seems very insecure and probably not a very good idea.
You could look at the plugins database and see if there are any plugins for authentication that would allow for this.
