Chris.
In your profile (click the 'profile' button at the top of the screen) under the section entitled "Preferances" there is an option that says 'Always attach signiture'.
Make sure that you have that enabled, the signiture should be in all your posts if you have that option enabled, and when you change it ... it will change as well.
Right now you have an image of portman and something that says 'FYC: Natalie Portman; also for Garden State'
You have swayed me btw ... ill nominate her when i send in my ballot
