NYCPHP Meetup

Hello NYPHP,
Does anyone know where I might find a simple "email signup" script? 
Basically, someone comes to the site, signs up their email address, and 
then gets an email with a confirmation link. When they click on that link, 
the fact that the email address was confirmed is recorded in the database. 
That's all I really need. I know there are full-fledged systems that do 
much more than that, but all I really need is this piece (if possible). I 
checked Sourceforge and also Googled, but didn't find much. Simple to read 
through and understand would be great too. Any ideas?
Thanks!
Harvey
