I'm using V2.
You can view it in action here
(There will be a popup music player. . just X it out)
Then scroll down along the right column is a graphic and form for opting in to the mailing list. Under that on the graphic is information about signing up for text alerts. Click where it says CLICK HERE in the star. . then you'll see your pop up box in action.
I want to be rid of the scroll bar showing in the popup window. . I'm trying to get away from having the "powered by" information be shown in the window. .. again, I have no control over the information being shown in the popup. . it is generated by the service and I can not alter the html.
