Hi Carol,
Each of the assignments was submitted from the same email address. I think one of my initial submissions (to "nitpick"), and one or two of my follow-up submissions to individual nitpickers, were possibly eaten by the spam filter. There doesn't seem to be any
pattern. I'm probably just being paranoid, but I thought maybe something about my email address is attracting the attention of the filter algorithm. I'll keep using my same email account for now and see if it happens again...maybe it was just a fluke.
Thanks!
