Reply To: INTENSE WIKI SPAM
okay! update: i found a mediawiki extension, confirmaccount, that works in the same kind of way as the forum’s system. it would require some extra installation and configuration, but so would reCAPTCHA, so whatever. whichever system folks would prefer can be used, i think!
eta: confirmaccount is kinda complicated and there are a few known bugs, so i guess that should be considered in the decision, as well. you can read about that yourself here.
