At this time I require a very small app but I need someone who can manage my complete Facebook program I have many affiliates and require much support. At this time I require an app that allows me to send FB friends a message asking them to like my page I want a button that automatically creates a like on my page without having to visit the page they simply click and they are added as fans. I need to ability to easily change the Fan page and the message I have many pages and friends. I am not technical so I need an app easy to manage for all the pages I have auto software to send message I only need an app to manage the like button for different fan pages
