Sorry about the recent string of spam emails coming from this group. I
removed all of those messages, reported them as spam and changed the
group settings to require people to now request an invitation to join.
That should largely eliminate the problem.
I'm also sorry it's taken me so long to wrap up the sheet, but I'm
hard at work on the last updates and expect to release the final
version in the next few weeks. Stay tuned!
