I have a almost complete joomla module where you can signup. The basic version of the module is able to synchronize a user to one campagin-monitor-subscriber-list. (all works fine...)
The advance version allows to create several list in backend of the module, and in the frontend let the user select which of the list they want to subscribe to. (one or more) The module frontend can be seen here: [url removed, login to view]
The only part missing, is the part where the selected newsletters are handled:
"Foreach selected newsletter, signup the user to the list at campaign monitor".
I have a test-site and campaignmonitor-testaccount setup with access to do the tests needed.
Im on messenger and google Talk, to provide any help needed.
