I tried this and noticed that "reuse" citation was nonfunctional (greyed out). Am very happy about that as I do not want bad ref names like <nowiki><ref name=":0"/></nowiki> becoming even more widespread. Please do not enable that, until those dysfunctional ref names are eliminated.
I'll also note that I tried to type that ref name in Wiki-markup and this software interrupted me and demanded I add an actual citation. I was only able to get around that interruption and type what I just did, by typing " ref name=":0"/>" and then going back and adding the "<" at the beginning. So apparently manually re-using citations is not easy in this editor, whatever it is. Hm. ~~~~
And my signature doesn't work?
How do I preview?? Wow I have no idea how this thing works.
I use a Mac with 10.12.4 (16E195) and am using Chrome for mac 58.0.3029.96 (64-bit) and I am using the default skin, whatever that is.
