Talk:In re

Colon or no colon?
Various articles, including this one, are inconsistent on the matter of following In re with a colon. Omitting it seems to be the majority use, but is there any actual preferred style? The search results I've gotten just confuse matters, with a whole lot of hits for "re:" as in email (even when I put "in re" in quotes)... -- Perey (talk) 06:37, 28 February 2016 (UTC)
