I'm sure everyone likes to use them, so I'll just say this:
At the moment, your signature might not show up until you switch it being viewed from on to off and back again. Dunno why, but that's how mine worked. So if yours doesn't show up, try that, and from your next post on it should appear.
We'll try to get that fixed if more problems are reported and it isn't just me.
