Special:Badtitle/NS90:All The Tropes talk:Copyrights/TVT Copypasta: best practices?

I was the only substantial contributor to the TV Tropes work pages for Thwaite, FHBG, Who Moved My Cheese?, and Who Cut the Cheese?. So I converted them to MediaWiki syntax and pasted them here as new pages. Now I see a note in Deist Zealot's talk page about a similar conversion, which transcludes TVT Copypasta. In turn, this template accuses failure to attribute the source. I can see how this might become a problem, both for ATT legally and for contributors unsure of how to avoid the appearance of impropriety. So I'd like to see some sort of guidance in this policy page about how to express the attribution for an import of one's own TV Tropes work pages, as well as clarification on whether formatting fixes and the like are copyrightable (I doubt it).
