Hang tight with the sig.
If you set it up when logged in that's good.
When I set mine up, and whenever I make changes, it takes a while for it to show up. Like maybe the next day or something. It adds the sig to new posts. I'm pretty sure it doesn't change existing posts.

Of course it only adds sig to any new posts if you log in before posting them. But you know that.
