I love the idea of this hack, I am just worried about ticking off people who would loose threir subsriptions. I'm not sure this is even possible, but...
Instead of unsubscribing all the subscribed threads, would their be a way to temporarily move them into a usergroup called something like: Bad email address
and have that usergroup recieve no e-mail? (besides account related e-mail, like lost password etc..) But keep the subcription info intact with no e-mail notification?
And then have an option for them to update their e-mail address, once it is updated, have the script move their susbcription status back to previous usergroup?
I hope that makes sense?
Again, maybe this is not possible, but I think this would be a great addition if it was possible
Thanks
