Membership signup process with Aweber looks so damn stupid!

OK, so I'm building a free membership site to collect Email and build my list using Aweber but the whole process look so damn stupid!

First I used the email parser to add people to my Aweber list at the same time they signup to my blog but then people were sent 2 emails. The Aweber double opt-in confirm email and the login info from my WP membership plugin. Which I thought looked a little weird that people needed to confirm at the same time they're getting their login info.

So to bypass all those emails I put in the Aweber form first so that way I wouldn't need the double opt-in but now people have to put in their name and Email twice. Once for the Aweber form and once more for my membership plugin.

Here's my question; is there a way to streamline the whole process so people don't give up half way through registering to my blog?

I've heard of a script that can prefill the membership plugin form with the aweber form so that people only need to choose their username and password. Has anyone heard of it and knows where I can get it?

Basically what I want is after people signup with the Aweber form, by putting their name and Email, all they should have to do on the next page is choose their username and password.

And if you know an even easier way where people can signup to my membership on one page and still by added to an autoresponder without all those annoying emails and extra steps, then please let me know how.

Thank you for taking the time to read my thread,
