Thread:Project:Support desk/Article expiry and access restriction

My team is considering setting up a MediaWiki wiki to share knowledge and manage information within the team.

Two features the team have expressed an interest in having as part of any new system are:

Access restriction for certain pages/items. Occasionally there may be a need to restrict some members of the team from viewing specific pages, perhaps relating to performance management or interview schedules/results. Does MediaWiki cater for this? I know you can lock pages to make them uneditable, but I'm not so sure you can hide them from being viewed altogether?

Document Expiry. It would be great to have an alert telling you that a page has been untouched for say, 12 months, and as a result may be out of date - flagging it for review or deletion to keep wiki content current. Does MediaWiki have this ability, or is there an extension that enables it?

Cheers for any help you can provide, or any extensions you can point me towards.

Dave.
