Hi folks,
I'm building a PHP/MySQL database for a customer. It's an advanced mailing
list for a band. They want to be able to send e-mails targetted to people
around where a gig takes place. For instance, if a concert is taking place
somewhere in the 42071 zipcode, they want to e-mail everyone within 500
miles of 42071. The database will have around 10,000 members, with e-mail
and mailing addresses.
Does anyone have a good idea for this?
Thanks a ton,
John Thile (gilrain)
