[Plugin: WordPress Mailing List Builder] Plugin forces confirm opt-in

Hi,

Nice plugin, it works great on my blog, however; I have a small problem.

I have disabled the “confirm opt-in” (double opt-in) setting in my getresponse control panel. This means that subscribers don’t have to confirm their subscription to join my list.

When I use a regular getresponse form for the same campaign on a different site, the subscriber doesn’t receive a confirm opt-in email message, but when I use this plugin on my wordpress blog for some reason the subscriber gets a confirm opt-in message.

Does anyone know how to disable this behavior from the plugin files?

Thanks..

Carlos
