Suggestion Idea: I think if you allow signatures to be attached to every post you make, the posts beforehand should be modified with your signature
Specifics: When you press the add signature to every post button, the sig will go to all poast posts. Also, when you change your sig, it'lll change for every post.
Why it is needed: Only about half of your posts will hav your sig.
