Just saw Frossa's topic, I think that if we go for square pictures then we should downgrade to IPB3. The round is much better with IPB4, and the square with IPB3
I disagree. I'm on other IPB4 forums, and when they all first made the switch, they kept the square avatars.
The circle avatars cut away from the avatar, and generally don't match the Minecraft theme. Where as square avatars keep everything in the avatar, and is a lot more Minecraft-like.
