Just an idea War:
We're all gentlemen here. Would it be a bad idea to open the roster spreadsheet to everyone? That way when you Add/Drop a player you can update your own list yourself. If the list isn't updated, then you never made the transfer.
As I said, we're all adults and sporting gentlemen. We should be able to trust each other, especially since all of us are (or should be) keeping track of their team at home.
That may take a little bit of the workload off of you.
We keep track of our own transactions, table, and scoring in the Championship. It has worked fine for us and stays pretty updated, since Atom is busy with architecture school.
I do the transactions, I think Mick does the table, and we all do our own scores that someone usually compiles into one post. It is pretty efficient.
In fact, I have scored over 200 points every week, since we started keeping track on our own.
