Testers Needed

I've put together an XLS for doing PBeM games using the Vector Movement
System.

What I need now are testers to try and break it. I would prefer that they have
at least some experience in PBeM games.

NOTE: This is not a final version, so please don't respond just because you
want a copy for yourself. When I've got a functional version, I'll put out the
call for all takers.
