The only reason people on zam have an updated signature with the new server name is because they had their signature in their profile before the new servers merged. My signature is an example of this. For me, my signature updated by itself when the servers merged/changed. I'm assuming since I had mine it works perfectly fine, but for people just now wanting their signatures, they cannot get it to work since the server list is no longer current. This is more of a zam issue you'd have to take up with the mods. I have no idea how to go about it any other way.
