Merge private/public Subscriber lists [SOLVED]

I have a number of private lists to which I have been sending campaigns, I would like to add these to a public newsletter list but short of exporting and re-importing I can’t see how to merge lists.

Is there a more elegant method than the one described above.


Ok I found it,
SUBSCRIBER LISTS -> click + to view members
scroll to bottom of page (this is what lost me ;))

there you will find options to merge the list

Hi, you should be able to use the private/public checkbox in the lists page
