These are identical messages on the Marathi Wikipedia that can be deleted because they are exactly the same. This is a job that any local admin can perform. It will make sure that when a message is changed, the updated message will become available. There is even a list that can be used to have a bot delete these messages; this may save someone from a lot of boring work.
Really interesting are the custom messages; they are the ones where the local message differs from the message provided by MediaWiki. They come in two flavours:
- Messages that are correct on any Wiki and should be included at translatewiki.net
- Messages that are specific to this Wiki
When the messages that are correct on any wiki are included at translatewiki.net, they will become available within a couple of days thanks to the LocalisationUpdate process. At that time these messages can be safely deleted.
