Arbiter and the Over-riding of Blocks.

[sdoebler]

I help assign for a large area and am unaware of a "firm" block. The ability to override basically any block exists. You can see a list of officials, available officials, potential officials, and issue summary. Basically it tells you the reason that they are blocked. Generally assignors call the person and ask if they can override the block and assign them, but not everyone follows this protocol.
