I've been getting a lot of questions about the Gmail Signatures add-on, so I've decided to go ahead and revive the project. That said, I am only working on it as a hobby, and I have a family to support, so development on this project comes in a distant second to all other obligations. In other words, enjoy the add-on, feel free to make suggestions and report any bugs, but be patient with me if it takes a long time to get things implemented.
