Dumb question for anyone and everyone

[littlecricket2]

Hey everyone,

I recently saved a new signature in my profile. Quick question: why would it show up in some new posts and not in others? I think I've actually seen it in exactly one post. But who knows? Maybe it'll show up here. Seems rather random. It does appear saved when I go to the control panel and check my profile. (It's the Ani DiFranco quote).

Thanks,
*Lisa Anne* (just in case)
