==Spam blocking: Questy Captcha==
I see you've spambots making lots of new accounts and occasionally making spam pages. ([[Special:RecentChanges]])
I installed ConfirmEdit (it's free-as-in-freedom) on my wiki ( ) and spam has dropped to nearly zero.  ConfirmEdit offers a few captchas but I think QuestyCaptcha is by far the best.  It requires new contributors to answer a question if they want to edit anonymously or make an account.  There are no questions supplied, so each wiki has to write their own.  The result is simple for a human but practically impossible for a bot.
Rough HOWTO:
# Download it here:
# mv ConfirmEdit-MW1.17-r77902.tar.gz WIKIDIRECTORY/extensions/
# untar it there
# Put these lines at the end of LocalSettings.php (change or add as many questions as you like):
require_once( "$IP/extensions/ConfirmEdit/ConfirmEdit.php" );
require_once( "$IP/extensions/ConfirmEdit/QuestyCaptcha.php");
$wgCaptchaClass = 'QuestyCaptcha';
$wgCaptchaQuestions[] = array( 'question' => "What colour is grass", 'answer' => "green" );
$wgCaptchaQuestions[] = array( 'question' => "What do most people sleep in at night? (3 letters)", 'answer' => "bed" );
&nbsp; &nbsp; 5. In WIKIDIRECTORY/extensions/ConfirmEdit/ConfirmEdit.php, make two changes:<br />
*Search for the following, and change it to "true":
$wgGroupPermissions['user'        ]['skipcaptcha'] = false;
*Search for the following, and change it also to "true":
$wgCaptchaTriggers['edit']          = false; // Would check on every edit
I do still get a trickle of spam, which I found surprising.  Maybe some of the spam networks that target my wiki include groups of humans, but only a small fraction have good enough English to answer my silly questions.
In contrast, requiring email confirmation is inconvenient for well-intentioned visitors and probably doesn't block any spambots.  Automating the response is probably trivial for a spambot author (although I haven't tested to see if it does reduce spam).  In any case, QuestyCaptcha should be enough.
Hope that helps, and best of luck with GNU MediaGoblin! [[User:Ciaran|Ciaran]] 17:58, 2 May 2012 (EDT)
It's been setup. Thanks. [[User:simonft|simonft]] Feb 20 2013
