This is a quick application to get up and running with your startup. It is written in Ruby on Rails for anyone looking to collect user emails and gauge interest before launching. We (@mikebabb and I), needed an application that provided signup for two types of users. Nothing on the market was really available for this… so we built it. Please fork and enjoy. I'm sure that someone will find bugs. I'm even more sure that someone in the community will make it even more awesome. It may have a bit of our content, but it wouldn't take you too long to change it to fit your need. Just a heads up. Cheers!

Here is an example of the launchpage once it's all styled/designed: Backstagr

Features:
1.Email collection for two types of users
2.Social sharing
3. Auto mailer
4. Ability to export user emails via CSV

Items you should change to customise it for your needs (baring the obvious. I'm not listing those. You'll see the title, etc.):

1. The .gitignore includes the mail initializer because it contains passwords/usernames etc. Here is the layout for stmp through google. Just fill with your own information:

require 'development_mail_interceptor'

ActionMailer::Base.smtp_settings = {
	:address			=> "smtp.gmail.com",
	:port					=> 587,
	:domain 			=> "mydomain",
	:user_name 		=> "myuser@mydomain.com",
	:password 		=> "mypassword",
	:authenticaton => "plain",
	:enable_starttls_auto => true
}

ActionMailer::Base.default_url_options[:host] = "localhost:3000"
ActionMailer::Base.register_interceptor(DevelopmentMailInterceptor) if Rails.env.development?

2. You'll want to go into app/views/static/success and change the details of the social plugins to match your domain/twitter/facebook.
