oh ok gotcha. The DLs can be nested if you want to merge two DLs into one. There's not way to
select and copy specific members. Export the two DLs (File>Save As>Save as
type=Text Only), making them Tab Separated Values files, open them with
Excel and merge them there. Then create a new DL, click Select Members.
Return to the Excel window, select all the name/address pairs, click
Edit>Copy, return to the Select Members dialogue and paste the selection
into the Members field. Hope this helps
