New rules: only cookies that are "strictly necessary" may be set
without permission. All others require explicit permission from the
user.
These will be quite a lot of work (to say the least) for commercial
sites with ads to comply with.
But UK-based MediaWiki sites should be OK, shouldn't they? Does
MediaWiki use cookies for anything other than login functionality? Not
sure if the "You must have cookies enabled to log in to SITENAME" bit
will need rewording for tediously strict compliance.
