I've had a couple of faculty flummoxed by the new bMail Compose
interface; one of them wrote me last night with the subject header,
"Google Mail Hell." Not everyone in our department has had it rolled
out to them so you may not know what I'm talking about, but be warned
that if you're on bMail (or personal Gmail) it's coming.
Messages you send to this mailing list are public and world-viewable, and the list's archives can be browsed and searched on the Internet. This means these messages can be viewed by (among others) your bosses, prospective employers, and people who have known you in the past.
