Okay, so this is the first time I am using WP, so please bare with me. I have installed WP and now want to create a custom landing page in WP so that the url is mydomain.com/landing-page On this page, I want a popup (using JS or something?) that will ask the user for their email before gonig to the landing page. I want the email to be saved in a file as a list in WP somewhere or on my server... What is the best way to do this? Any help would be great!
