Display custom message or redirect to joomla article upon registration

Hi there

I am trying to activate registrations (using quick registration form) and i am able to change the setting so new users can register, and upon registration an email is triggered to both the designated Admin email and also to the new user. However, upon registration, the person receives a joomla error 'Please login first', and it is not clear if the registration was in fact successful.

Am i missing something in my set up or do i have a setting configured wrongly to cause this?

How do i either a) customise the error following registration to confirm the user has registered successfully and to explain what will happen next or b) how can i redirect upon registration to an article with this information?

Thanks

Paul
