== Warning  (it's a new one  at least, to me)  == 

 Recently I tried to save a certain edit (in article space), and I got a WARNING like the one shown here: https://en.wikipedia.org/wiki/MediaWiki_talk:Abusefilter-warning-archiveis#Edit_request_on_15_November_2013.E2.80.8E [1]  

 That was (iirc) the first time I had ever seen that warning.  (I was trying to add "or http://archive.today/Y00Gd" to the "Note" in footnote [3] of Hiloni).   

 I guess there is some more information available at a place [2] (an RFC?) that is pointed to by a link from inside the WARNING shown at [1].  That is, the place [2] is here: https://en.wikipedia.org/wiki/Wikipedia:Archive.is_RFC .  

 Now, most of this stuff is NEW to me.  I haven't read the RFC (yet), and I've only read part of the info at [1].   

 Any comments?
