$wgCaptchaTriggers['edit']          = true; 
$wgCaptchaTriggers['create']        = true; 
$wgCaptchaTriggers['addurl']        = true; 
$wgCaptchaTriggers['createaccount'] = true;
$wgCaptchaTriggers['badlogin']      = false;
维基添加了confirmedit这个插件，createaccount这个项目是创建账户的选项，ture意思是创建账户时出现验证码？待确认。因为edit和create的时候同样true，但不出现验证码。
