Hi Jorge,

Run a script to output all the email addresses and for each one send an email to? Should be easily handled with a perl or php script (or whatever your preferred scripting language is). Generate the email. Connect to database, get list of users with an address. For each user send the email to. I'd suggest you limit your testing to just you to begin with, otherwise you could unintentionally send a bad email out to all your users (which I'm sure they wouldn't be very happy with). HTH S
