Pop-up newsletter subscription Window for new visitors

[killua]

I already have an existing PHP FormMail newsletter subscription system where people can subscribe easily on all my pages.

Now, I'm seeing a lot of sites where they use this "Popup window" system so that new visitors will have their attention to it. And I would like to implement it in my site, too (only on certain pages).

Please I need a simple way to do it, maybe a nice good free script that I can simply do by myself. So let me know how?

I also have the following question:

1. Will this pop-up window system affect your search engine rankings? since if search engines visit your site, Google for example, Google will see the content of the pop-up window and not the actual page being visited?

2. Will this pop-up window affect pop-up blockers? Because if it does, then I think implementing it may be useless as most browsers block pop-ups.

I'm going to use this pop-up system only to gain more subscribers for our newsletters.

Most browsers block popups by default these days. I used to use pop-ups on a music magazine site to flash up changes to the published gig listings but gave that up many years ago once blocking became the default.
