Generally, I'd go with "da yo", but TBH I wouldn't worry about it because "dayo" is acceptable as well with some TLers. Stuff like dayo/dane vs. da yo/da ne isn't as big of an issue as the three big ones I pointed out before (n'n and tch and ru nda), as spacing is a hell of a lot more confusing to fix than actual spelling choices. For example, I'd probably accept both "nanika hen da yo" or "nanika hen dayo", with only a slight preference for the former.

Speaking of which, for the "ru nda" rule, be careful not to go off and change every single phrase out there to "runda". Some of them should be separated, such as "iitai koto ga arun da yo" (i.e. "runda" is okay, "run da" is okay, "ru nda" is not okay).

So yeah, focus on simple fixes for the big three for now, and we can leave the spacing issues for when a TLer comes up with an actual romaji guide for the Wikia.
