Hi all,
Recently, in order to make a rather small user interface change (see bug #42215), our team needed to replace MediaWiki:Welcomecreation with a new message, MediaWiki:Welcomecreation-msg.
The new message contains all of the things MediaWiki normally inserts in that message, and simply changes the header text. Simple enough.
My question here is... Is there a best practice for advertising changes to MediaWiki messages like these?
This message, which is given to users once after they register, is sometimes customized. We can go look and see which wikis have written custom content, and inform them they need to migrate it to the new message. But I was wondering if others have encountered this problem, and how they dealt with it.
