Review for Signature by StormKnight
Rated 5 out of 5 stars
A definite most essential addon. Its been very abandoned. I've tried to contact author and even offer a donation. ;(
In the mean time or in light of someone to take this over here is a way to make it work. While its meant for authors/developers it makes most of our old addons work. ;~)
