Hi,
I have modified the text timer and I have sent you an email with the file modified. It is the file scripts_video.js. Replaced it by yours in the folder js.
About the subscription form, Mailchimp is a provider of email marketing. It is a great tool. The other option is a simple form. The difference between both is that Mailchimp checks if the user is already subscribed. The other option doesn’t check if the email is subscribed because the emails are not saved in any database.
Regards
