Hi, I am looking for a simple way to implement simple "coming soon" (pre-launch) page for my project on Ruby on Rails. User should be able to leave an email in order to be notified when project is launched.
Is there such a plugin\gem? Or I should do it myself...
I hope people don't interpret this as shameless self-promotion but I've just implemented exactly that functionality in a web service. It's called ComingSoonApp http://comingsoonapp.com. Besides capturing the email addresses, it also embeds your google analytics code so that you can see how traffic is building to your site.
Launching Soon is a rails plugin. It also integrates with MailChimp or Campaign monitor.
Similar to Coming Soon like the other answer, I use a product (I don't work for them) called Prefinery. http://www.prefinery.com/. It lets you put up a form on your site (you just include some javascript) and beta testers can sign up. I've used it at my site www.mealszen.com if you want to see what it looks like
