Over the weekend, as many of you will have noticed, we had some problems with the website. Now my email is not working particularly well. If you sent me something urgent in the last 5 days, it might be worth resending it to bw93-at-cornell-edu. I hope this account at least is working.

Sorry for the inconvenience. Regular service will return shortly etc.

We seem to have lost some data from while I was away over the weekend. Sorry about this – I don’t know quite what happened. Anyway, use this for any announcements, including announcements that were on the threads that somehow got deleted.
