Thread:Project:Support desk/ConfirmEdit do not work/reply

Which release of ConfirmEdit did you install? For MW1.16 you should be using: http://svn.wikimedia.org/svnroot/mediawiki/branches/REL1_16/extensions/ConfirmEdit/

I should also note that MW1.16 is no longer supported and you should consider upgrading to MW1.18.
