Guild Wars 2

The snow blocks for Wintersday appear gray and not white, I assume everyone is aware and this will soon be fixed

Is there a way to change the name of your guild, and retain the guild, without starting over?

There seems to be a flaw with trading. I posted unidentified dye at say 2 silver. The trading post lists unidentified dye at 6 silver. The post should always list the lowest available price. When the item is sold the next lowest price should be offered and so on.
