Check/UnCheck All List only work when lists are shown on the "Manage your email subscription" page.
also when linking to manage your subscription it does not display all the lists one maybe optin for, it only displays the list where one can optin to.
I am not sure but i think a previous version displayied all the list the subscriber was listed in so he could actually manage his account. Now the only lists that display for both to optin or optout are the lists checked in the general settings.
When a user wants to manage his account he should be able to see all lists he is opted in even if not checked in general settings.
I hope i made sense out of this, can anyone take part.
