I’ve enabled captchas on the site, using the WordPress plugin here.  The site was gathering a few hundred spams a day for moderation, which is just too annoying.  I’ve selected numbers only, no words, because Chin Yi’s postings are in traditional Chinese , and that’s the native language of this WordPress installation… it might confuse English visitors to be asked to solve for X in:  X – 六 = 9

I’ll be watching the moderation queue for indications of problems.
