How do I add a signature?

[Necrotic]

Hello there, I am curious about how to add a signature to my account. I'd like to make sure it's known that I am paypal verified and such and would like that to be shown in my sig. Do I need to purchase something to unlock that feature?

The default membership group cannot add sigs. To upgrade go here
