automatic weekly e-mail reminder

I'd like to set up an e-mail reminder that would be sent out to a list of members automatically at the start of every week. The reminder message would be the same each week, but I may need to add new e-mail address periodically. Is there a simple way to do this task? If you know of a good source that I can take a look at to get started, let me know. Thanks in advance for your help.

Are you doing this from your own server or through a hosting company?

All you have to do is setup a Cron job to automatically take a list of e-mail address from a database and send an e-mail to each of them. You could then create a Perl or PHP script that would allow you to add/remove e-mail addresses.

I have created a Perl script myself that takes a list of e-mail addresses from a mySQL database and send's out a customized list of stock quotes at close of market every weekday. I have also setup a site with PHP that allows users to register with their e-mail address and choose what quotes they want.
