I was thinking of creating a logon screen, so you can login, then be presented with 2 text boxs, where you enter the subject, and message content. Then when you press send, it would run a query, and get all the address from the $e_mail field in MySQL, put them all in an array, and send the html page, to each e-mail address. Of course I then have the problem of bounce back e-mail, where I'd have to write a script to remove all bounced e-mail address's from the database.
Another way, would be to make a shell script, crontab it to run once a onth or whatever, and upload a text file with the subject and message content.
I'm just thinking of the best ways to run it.
Any other ideas?
