A quick FYI update - The sheet was submitted for approval to the roll20 devs last night so should be available for all to use on roll20 in the coming days. For full info see the thread on the roll20 forums linked below....in the meantime i'm off to do some work I get paid for a couple of weeks (though i'd much rather be doing this!)
