Thread:Talk:Flow Portal/Subpage scratchpads?

Will this affect all pages in talk namespaces if it is rolled out Wiki-wide on one of the wikis, or can this be selectively (de-)activated? I know that on English Wikipedia, some people use the talknamespaces to store scratchpad information in subpages, while developing drafts on the subjectspace subpages. -- 65.94.76.126 12:08, 24 May 2013 (UTC)
