Hello,
CommonsTicker is a special tool created by (commons:,meta:,:de:w:)User:Duesentrieb to allow for greater communication and transparency between the Commons and local projects (all projects, all languages) that use the Commons. When it is set up, a log page is created and a bot posts updates about any critical events that occur to any Commons images that are being used by that project. Critical events are: image replacement (a new version of an image being uploaded over the top of an existing one), an image being marked or unmarked with a deletion tag (including no source, etc), and an image being deleted.
This allows local project users to immediately identify any images that have been nominated for deletion, giving them plenty of notice to take part in the deletion discussion, as well as checking that image replacements are not vandalism and removing any red links from deleted images.
CommonsTicker is completely translatable (if you provide a translation). All it needs to be set up is a project admin to "sponsor" it through the early days. Now taking requests! :)

(Note that it will not be possible to set up on English Wikipedia until the toolserver issue is resolved. But since this is supposed to be a list for all the Wikipedias, hopefully this message is useful to some people at least.)
cheers, Brianna (commons:user:pfctdayelise)
