Please help, it is pretty confusing to me how it works.
I integrated it as described above, forcefully=off.
Have radio buttons (yes and no) on profile and registration page.
OK, but what happend is this: When everything was setup right (I guessed) I ran the Scheduled task for vBulletinMailChimp. Took quite some time (1000 members) and ended in an MySQL error. But guessed that most of the mails we're sent. Pretty soon I got some MailChimp-Yippeee mails for new signups.
But I wondered what would happen when the scheduled task would run the next time. So half an hour later, I manually ran it again. And OOPS, I noticed that it starting to send out all (??) mails again. That's ofcourse not what I want, and especially not what my forummembers want

The sched.task is turned off now.
What can I expect that this plugin does?
And what happens with new forum registrations when the sched.task is turned off?
Hope for some extra info on this promising plugin ...
Thanks in advance!
