Very simple to use but yet powerful!
Maybe in the next version the admin user could change IPs (otherwise you always have to change the infos with PhpMyAdmin, and that's not very fast ;). I've not seen an option where you can block IPs yet ...

Good extension, very simple to install and to use, I liked it over all those I've tried. Maybe you could add a text field where you can specify what the module should display after the countdown has expired? And also you could let the user choice if he wants a line break before the days and after the seconds remaining.

I can't give it a rating because it doesn't work for me: I can't edit the descriptions and insert text in the textareas. Please fix it as soon as possible, I think it could be a great extension!
