Allow the ability to archive wikis. Once a wiki is not needed, it should be archived. However, if this wiki is needed again, it can be activated again so that the end user sees it. If you have a community for IT wikis, this feature would be more than Beneficial. We currently have to move the wikis to the trash or delete them and create them again. That's a little bit of an effort. It would be great if there was an Archive View. Similar to the Recycle Bin.
The whole thing could be combined with an expiration date. See this idea. #BigNeed
