How it works:
 - client mod written in java, dependent on Forge, installed by installer or manual install in /mods folder of minecraft directory
 - client mod can be installed with a one-click java installer... checks to see if user already has Forge.  Back's up minecraft.jar
 - client mod requires user registration
 - client mod has GUI accessed by 'm' key and has overlay elements that the user can disable/enable
 - client mod allows users to follow other users and create 'friendships'
 - client mod allows friends to message each other
 - client mod allows users to vote on servers they like, to see popular servers and see which servers their friends are online
 - client mod allows users to see when their friends are online and what server their friends are on, and to join them
 - client utilizes web-sockets to enable notifications of online friends, new messages, new images, votes, etc.
 - client allows user to take a snapshot of their minecraft game play (images) and share with friends, comments, voting
 - supported by extensive back-end services, also created by mod developer
 - companion iPhone app going through iTunes approval process....should be available to public within next 2-3 weeks
 - companion iPhone app is optional, there is no requirement for user to have the iPhone app...they only need the client mod
 - client/server has considerable security features to prevent malicious and accidental harm to user data
 - at no time does the client ever ask for, see, get access to, or store the user's minecraft.net password
 - client mod does not have easter eggs, cheats and does not, nor ever will, negatively affect gameplayer
