Enable/Disable Signature [solved]

I have a forum with some pals, it owns. Thanks for hosting such services, it's great guys!

To the point..
So we decided to have a Sig contest, but the problem is Sigs aren't enabled automaticly (you have to check in in the extra options under the post).

I have found a tutorial posted by The Godfather about how to enable them.
But I'm afraid that tutorial is out of date, cause I can't find the steps he gave to follow in the latest admin controls.

Could someone tell me how to enable Sigs in every post? (with screenie or step-by-step in the admin controls)

Thanks.
