Signature Not Showing Up

I made a signature with the dates of their DACA stuff like everyone is doing but mine is not showing up. I went to Control Panel and saved the signature and everything but it's still not showing up. Can anyone help?

Never mind, I see it's showing up for new posts but not my old ones.

EDIT: Ok, I see. In my old posts, the show signature box is not checked. Any way to retroactively check that box for all my old posts as opposed to checking it one by one?

^ No idea. Probably a setting with the website that needs to be changed and that's only something Nick can do.

Alright Swim, I'll go ahead and PM Nick.

how do you do the signature?

I was just wondering about the signature thing until I found this thread.
Now I see my sig....ewww....immana have to pretty it up =)
