Thank you for this nice plugin. I encounter the following issue. I created 3 lists. 2 are private and one is public. In the widget only the public one shows up. When people register to the public list through the widget, they also get registered on the 2 private lists automatically.
I tried to make the 2 private lists public, and create a form not showing the 2 lists. Same problem. People get registred to all the 3 lists. Actully no matter wht I try, I cnnot get people to register to only one list. I have read all your documentation and cannot find a solution. Thnks a lot for your help.
