Allow A Method To Cancel Guild Creation

I wanted to see if the guild title Exp was available, so I started the creation of a guild via the guild hall. Then I typed in the tag and realized it wasn't available. I tried to cancel it a few times but there didn't really seem to be a way how. If disconnecting or using /class is the only method, this simply is not sufficient. I eventually attempted dropping my liquid emeralds on the ground and then entering in a tag that would work, and it did cancel but once the cancel message completed, my liquid emeralds that were on the ground were deleted?!?

Either way, an actual cancellation method is required.
