I have English Teacher X's obra prima to read next and have enjoyed the other ebooks - they include a lot of sensible and realistic advice - but I didn't enjoy Speaking Activities that Don't Suck as much.

I was having lunch a few months ago when I suddenly struggled to get to the end of what I was saying- my voice dipped and wouldn't come back. Within a week or so, I couldn't produce any noise and was forced into a soundless whisper. If I strained a bit, I could just about make a sound that could possibly be heard at very close range. My first medical consultation did nothing, and I had tickets to go abroad that meant going with just this silent croak.

A couple of weeks ago, we blocked access to the forum from all IPs from South Korea. The forum had been under attack by some organised spammers for a few weeks, and it was ruining the forum. The attack was, presumably, using something like a botnet as there was a seemingly unending supply of different IPs used. Day after day, hundreds and hundreds of posts were being made and it was impossible to keep up with deleting and banning the accounts posting the spam. This was affecting the forum- people were complaining, and many were simply put off by finding page after page of nonsensical messages. The spam filter was not catching a lot of the messages as most didn't contain links but text pointing towards sites that were probably full of malware.
