Foundation policy states that each project must have a strict minimum of two CheckUsers or none at all, and that each must receive a minimum of 25 support votes. These measures are intended to protect editors' privacy by limiting CheckUser access to a relatively small number of users. Despite prior assurances from steward Datrio, it seems likely that the 25-support rule will be strictly enforced over Wikisource's request. The two candidates, Pathoschild and Zhaladshar, currently have 18 and 14 votes respectively.
Concerns with the current policy prompted a discussion on the Wikimedia Foundation mailing list (see "[Foundation-l] Stewards are ignoring requests for CheckUser information?", 14 April 2006), where the concept of "guest CheckUsers" was proposed. This proposal would give CheckUsers access on all projects of a language, and allow them to perform local CheckUser duties on a smaller project with the community's permission. The proposal is currently being discussed under "Access (new version)" on the CheckUser Policy talk page.
