Personal and Organization Profiles
Personal Profile- A personal profile is just as it sounds :) This is your individual profile for yourself or your character/avatar in the game you play. You can have multiple profiles for each of your characters that are separate from one another and operable as such. You can easily switch between profiles to check for messages etc.
Organization Profile- These are like a page on social networks where you can comment as and create content as that page. Perfect for a virtual business, guild, or performers etc. Same thing, you can have multiple and switch between them under one account.
