Here's another sample you can download and hopefully learn something from... or maybe you know a better way of doing this and can let us all know too!
This is a simple CSV Import/Export configuration which uses the same Subscriptions table I have in the Double Opt-In Subscription configuration sample. Table info is in this config too.
There's no lists show, no completed messages - it's just a straight select a file and import, or click to export setup.
I keep the format for both CSV files the same, as it seems to be a simple way for people to grab the format for import... just export it first and you pretty much have the template.
