Folks, bad news. I originally planned to at least attempt (and almost expected to succeed) in writing up a post for group2 today, but after my visit to the school office to work on a project I seem to have caught a cold and had to stay in bed for most of the afternoon. I'm crawling up from bed to inform you now - I feel a bit better, but I fear I might have to go curl back up in bed later. Sigh.
