sorry folks

somehow i got unsubbed from wsn for 2 weeks and was too busy to notice.
normally i send private messages to contributors suggesting that they
keep a civil tone and refrain from personal insults. this usually works,
though we had one hard case about 2 years ago.
please let me know if you have concerns about the list.
