Thread:Support/Translated messages not getting updated in Sa.wikipedia

Hi, I'm a bureaucrat on Sanskrit Wikipedia (sa.wikipedia.org), and an administrator noted that the translated messages on translatewiki.net were not getting updated frequently. As a result, he is now editing the messages locally on sa.wikipedia. I am concerned about this, because I don't know what complications will occur when a user now edits the interface messages on translatewiki.net. So my questions here are: 1) Is it possible to update the Mediawiki messages for Sanskrit language (sa) more frequently? and 2) Now that a user has edited some of the messages locally, what effect will it have for people trying to edit it on translatewiki.net? Thanks!
