Collecting emails from subscribers

I was thinking of the easiest way to collect emails from website visitors and I thought that a box where people can type in their emails is the easiest.

But is there a script that takes care of those submissions, at least by making a list, a flat text file would be even better.

Any suggestions?

Thanks!

 

The best way is to have a newsletter or subsciprtion script installed. if you need it,then PM me now...

if you also need 150k email ids to use for your purpose,then i can have it also.

 

Thanks for your offer, but I am looking at handling my clients only.

Anyway, I was looking for something more basic than a newsletter script.

But thanks again!
