I've added quite a lot of code to this module, in order to get it to do everything I need. The two main features I've added to it are:
- Backend UI for each mailing list, allowing individual name / email pairs to be listed and edited.
- Ability to import emails into a mailing list from a CSV file
I've also moved the admin area from 'admin/settings/mailing-list' to 'admin/build/mailing-list'.
Hope others find this patch useful - and if it's worth it, might even be good to get it committed back.
Note: this patch depends on these two other patches in the queue:
