I am looking for a good Wordpress plugin for signing up people to an optin list. Do you have any recommendations?
Ideally it would include at least the following:
a) Cookie support - So if the user chooses not to sign up, next time the visit the blog it won't popup again (or over and over and over, etc) (or maybe I can set it to display a maximum of say 5 times).
b) The "screen darkening" thing. While not essential, maybe where you have it where say after 15 seconds the screen darkens and it asks you to sign up
c) Obviously various (easy) customizations, such as inserting images/customizing the text, etc, etc.
