Signature not appearing?

Hi. My signature doesn't seem to be appearing on posts. I've already clicked yes to always display signature.

WhoNA disables the ability to use a signature. They prefer a "clean" appearance to the forum posts without all the extra space for signatures.

Why is it still a option under profile?

That kind of thing is part of the Forumotion forum templates. It cannot be "removed" but it can be engaged or disengaged by the individual forums.
