I'd like to make a suggestion (shocker!)
I want it so the default is blank (no mood), and in postbit nothing shows up.
Then, for logged in user, they (and only themselves) will see an option like "Set your mood" so they can set the mood.
This way the people that want to use it can. But for everyone else, it is blank to begin with and stays blank until it is set by the user.
I'm also on postbit legacy, and would appreciate a $forumhook that I can just input in where I want it.
