So far, I've only got this set up using the basic CGI script to subscribe/unsubscribe, along with using the control panel. Unfortunately, the control panel doesn't show subscriptions in progress, nor does it gives a way to re-send the request or cancel it (so it can be re-submitted).
Does the API provide a way to cancel the request or force the re-generation of the request e-mail? That's what I really need.
I'm really concerned, because I'm going to be turning this on and importing in 800+ subscribers from our existing mailing list that we had with another hosting company. Being a cynic, I know there will be several that loose/delete the e-mail and then will want to subscribe. It's going to be kludgey telling them to just retry every couple of days - I know I'm going to get grief over that.
I understand and agree with the anti-spam policy, but so far I'm disappointed in the implementation of the "required" announcement list mechanism.
