OK, a bit more on this. I now have two lists. One is a re-homing update list. The second list is a general list.
Users are automatically added to the general list when they subscribe. They are NOT automatically added to the re-homing list.
After a user registers, if they go to a page with a Simple Opt In module, associated with the re-homing list.. it's not shown. I guess because they are subscribed to the Announcement list.
So, it appears that the Simple Opt In module will hide itself no matter what list the user subscribes to. Also, if they unsubscribe from all lists, it still stays hidden.
Is there a way to get the Simple Opt In module to only hide itself if the user is subscribed to the list associated with the Simple Opt In module?
The alternative is that I don't hide it from subscribed users, but then it's taking up valuable space and pestering users all the time. It also looks like they are not subscribed, when they are!
any help appreciated.
