Subscription and sign up


I am trying to set the Membership plugin and having trouble with the subscription and sign up process.

What I am trying to do is create a page where new users can sign up, fill in their details such as username/password and so on and then be taken straight to Paypal as part of the process.

Is this possible using Membership?

If so, how do I go about it. I have spent ages reading through the user manual and still not getting anywhere.

If someone can help, it would be greatly appreciated.
