I have my Aweber email sign up form appear as a popup when someone visits my site. It also seems to "pop up" when people dig in to the site and visit other pages - something, I wish it didn't do. I have gotten complaints, too, that the form keeps popping up even after someone joins the list.
Is there a way to make it appear only when someone visits the main page - and disappear permanently once someone signs up? Any help/experiences or suggestions are much appreciated.
