Aweber Question - How can I automatically move someone from my squeeze page list to my buyers list?

What? It doesn't move them from prospect list to buyers list, it just moves them from prospect list to buyers list? That's basically what you just said.

You will notice in my post above I said:

"What this would mean for you is you can set it up so that when someone joins your buyers list they are automatically removed from your squeeze page list."

The way I have it setup is simple. Someone buys my product. The auto-responder list I have for my buyers is single optin so they do not have to confirm. The reason I have it single optin is because the email address they have just used to setup their membership access is the same email address we use for the autoresponder so it's highly likely that it is a genuine email address.

Upon payment they are taken to a thank you page that has a little box that says, confirm your email address to receive important product updates. There is a text box that already has their email address filled in. I have this setup to happen automatically. If they like they can change that email address or if the email address is already correct, all they need to do is click the 'Confirm' button and they are then added to the buyers list. At this same time they are then automatically removed from the prospect list (if they were on it).
