Got this working .. nice hack :)

Am I right in thinking that I should delete the "Activation Reminder Email" cron job?

yeah, you should. not the file but the cron.

Ta .. :)

OK, I've got to disable this thing temporarily until I can get some help. I installed this about two weeks ago and started receiving email that my site was spaming new registraints with up to 700 emails requiring them to click on the link (that was already expired) to activate their account.
I really want to get this thing running but I'm hesitant after pumeling a few of the new users with a ton of email.

Anyone got any ideas on what I might have missed that would cause this to happen?

my suggestion would be to install it, then register yourself and see just how many you receive.

Yeah I did that on the first report of this problem and had no problem. Then I had several others report the same problem and the issue seemed to be expanding exponentially. I had installed 5 hacks in the past 2 weeks so I started looking at these individually and when I got to this one I went through the instructions again and it finally dawned on me (I’m a little slow on the up take). I didn’t want to delete the old “activation” cron job until I saw this one working correctly so I just zeroed out all the timed fields in the task and that should do it right… Wrong! The activation was kicking off every minute and resetting the codes as it went on at its feverish pace. I changed the setting to run once a month (on the old cron) and will delete the task in two weeks if no more problems are reported.

Thanks!

for some reason, a user's name got reported twice in my email, like this
3 Day Reminder Sent To: Xantrix, Xantrix

also got this when i tried to run the cron manually to test it

Sent 5 Day email to Test1
Sent 5 Day email to McHavoc
Sent 3 Day email to Xantrix
Sent 3 Day email to Xantrix
Sent 3 Day email to Ensui

it's sent out twice to xantrix here too :( , does anyone know what's wrong?

think this could be an addon?

is it just that user that's getting special treatment?

could be but not by me.
