Bypassing the Payment Option

I am slowly getting there with this simple membership area.

I am wondering if there is a way to bypass the payment option. Since this is a 100% free membership area, I don't need them to "Subscribe" via PayPal or anything like that.

I would like it so when they put in their Name, Email, User, Password and Activation Code that it simply goes to the Welcome Page instead of the little popup that says "Subscription Name - Free" and they have to click the Subscribe button to gain access.

Again, is there anyway I can bypass this last step as it is very redundant.

Thanks,
Nathan
