Fixed the Six posts to use character info instead of the user account.
So if you want to use a separate username etc with your main account, you just have to fill out the Six username, title, avatar, signature etc.
If you have a dedicated account for the character (like I have for Steel, say), you can just put their info as normal - you don't have to put a seperate avatar, signature, character name, usertitle in the profile for them.
