Indeed. We've asked many people about this through both Private Messages and on the ZU Chat, and they have all agreed with the rules. We can't change it simply because there is a minority of people who cannot accept the fact that they have to either resize their signature images and reconfigure their signature's layout.

Bobslob, making the fourth line reserved only for giving credit to the signature maker (if there is one) would make for a good exception to the rule. I'm not sure if l-o-s can edit the current Announcement, but If he agrees, he can always re-post it with the new rule taken into account.
