I know a lot of people (including myself) have been asking for this so I thought I'd whip something up.
I need some people to test this as my local mail server seems to be on the fritz.
Drop the file into the /plugins folder, activate and then use the following to generate a link to the resend page:
<?php rae_create_link() ?>
If all is well, this should direct people to a page asking for their email. Once they enter this, they will be resent their original activation email again.
Thanks in advance for those who can help me test this. Once it's working okay, I'll put it up on my site with a full explanation.
