ConfirmEdit Extension Installed
We've already had a visit from a vadalbot since the migration to MediaWiki 1.9.3, so I've quickly added the Confirm Edit Extension which adds a CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) process which asks a simple mathematical question. This is the standard method used by Wikipedia and its sister projects rather than the more common method of reading obscured characters of text froman image. The reason for this is that there are standard programming libraries becomming commonly available which are able to read most of the CAPTCHA images that humans can read.
