On occasion it may prove necessary to remove material from Shifti. There isn't a formalized process for determining what to remove, as there often is on larger wikis, but there are some general guidelines one might find informative.
There are two methods of removing material from Shifti; blanking it as part of a routine edit, or deleting it from the database. Any user capable of editing a page is capable of blanking material in it as part of his or her edit, but only administrators are able to delete pages completely.
When an editor blanks some or all of a page without deleting the page, the removed material is still accessible via that page's "history" link. The edit history retains all previous versions of the page, so if something gets removed by this method any reader can still find it again with a little poking around and a non-administrator editor can restore it. To revert a page to an older version first navigate to the version you want to restore via the "history" link, then click "edit", and then immediately click "save".
Full deletion is different, in that the page "ceases to exist" as far as routine editor access is concerned. Links to the deleted page will appear red, as if the page had never been created in the first place, and there will be no visible version history. The deleted material can still be restored by an administrator later if need be, but you'll have to specifically request it.
Any author may remove his own stories whenever he likes, either by blanking them (a useful temporary measure) or by requesting that they be deleted. Blanking material on other pages should be done with more caution.
Administrative deletions may be done as part of routine housekeeping, for example to get rid of a mis-titled category page. Deletion doesn't actually save any disk space since deleted revisions are retained in a private database in case they need to be restored, so generally speaking "housekeeping" deletions should err on the side of caution; administrators should ask a page's creator whether a seemingly unused or useless page is really no longer wanted by them.
Material that obviously violates Shifti's policies or legal requirements may be deleted more promptly. For example, posting someone else's stories without explicit permission is a violation of copyright, and in this case administrators may err in the other direction and delete material without asking first. If a mistake is made, please don't get upset; deletions can be undone, just explain the situation and it can be worked out.
Requesting deletion and undeletion
There are many ways one may request deletion of a page. Any approach that makes it clear what your desire is will do, such as posting a request on an administrator's user talk page or blanking the page with an edit summary requesting deletion. However, to make deletion requests easier and more unambiguous, a template has been provided: Template:request deletion. Simply place the following text on any page you want deleted:
And this will display a notice and place the page into Category:requests for deletion to draw the attention of an administrator to it.
If a page has been deleted in error it is also possible for an administrator to undelete it without any loss of data. Please notify an administrator on their user talk page to get something undeleted.
