I just wanted to point out that if anyone is a user of dynamic questions with questycaptcha as per Jamie Thinglestad's implementation here: http://thingelstad.com/stopping-mediawiki-spam-with-dynamic-questy-captchas/
You may have noticed that recently, the spammers have figured it out and the new user account logs are filling up.
Well, Jamie has updated his solution: http://thingelstad.com/updated-dynamic-questy-captchas/
I've implemented it and so far so good.
Note that to get it to work, I had to change the => to => in the question and answer strings.
Cheers Bill
