It's my first time interacting with a server, so please bear with me... I want to install sendy (http://sendy.co/get-started) on a subdomain of a site I currently host on Heroku. I use a ubuntu 12.04 + Lamp droplet. I uploaded the provided 'sendy' folder to ```var/www/sendy```. I also used my DNSimple account to create a CNAME and A records that both redirect my subdomain to the server IP address. When I go to ```mysubdomain.mydomain.com/sendy```, nothing happens. Can anyone help me figure out what I'm missing here?
