Aweber always sending the confirmation email to user

This may not be on GF side but just in case I thought I'd ask. In Aweber I
have NO checked to sending a confirmation for the user to subscribe to my list, but,
every time I use GF it sends it no matter what. But if i use there form generator
and put the code on my site Aweber does NOT send the confirmation.

So is Aweber treating all forms that are using an API this way? I really don't want
to send a confirmation. If this is the case, how do most folks get around this?

I guess I could use their code for the first page by asking for email and first name and
have the thank you page be GF's next page but I would have to some how merge the
two later and that could get messy.

I have a call into Aweber...

The Opt-in condition has no bearing on what aweber does.

If you enable an opt-in condition would YOU set a condition in GF to decide to add the person to you list or not.

GF ALWAYS sends a double opt-in by design

From the documentation:

-Control opt-in and only add subscribers when a certain condition is met.
-Automatically sends a double opt in message to insure only legitimate subscribers are added.

I really think single or double opt-in should be my decision but Aweber for GF always sends double opt-in
