Yes, the "as already suggested" referred to the translatable message points, not the the part before it. Matt, there's no such a thing as "the appropriate village pump" for everything everywhere. You used as an example [[w:en:Wikipedia:MediaWiki messages]], too bad that only nl.wiki has something like that; and even on en.wiki it has only 87 watchers compared to 38 for the specific MediaWiki:Welcomecreation. You have to reach people who did or discussed a customization of the message/who follow system message changes, so post a message where they'll see it by checking RC/watchlist rather than digging kB of village pumps. I just sent a message about [[MediaWiki:Pageinfo-footer]] this morning (on its very obscure talk) and I had already good feedback from 3 wikis.
