In anticipation of the upgrade to vB4, and to enforce existing rules, we're going to be making a change to our signature policy and (re)enforcing it. You could also say this is a reinforcement of our existing policy.
The first stage of this will take place over the next week. We ask that you remove all spoiler tags from your signature. Additionally, we will be enforcing our rule about signature length. If it's taller than 160 pixels--about ten lines of regular-sized text--it is in violation of signature rules. In addition, the width limit is 575 pixels, and the total file size does not exceed 500kb.
We're giving you a week to allow you to take some time and sort out how your new sig will work. After this week, there will be an additional week where signatures not in compliance receive warnings. After that, we will be infracting people with the standard signature rule violation infraction.
The existing rules of a maximum of one large banner image or six sprites remain. If you have any questions or concerns, feel free to ask me about them.
