[member="Wolf"] The [Dark Jedi] tags are the best fit at this time until we someday get our own tags, hopefully.
I know, it sucks. And the reasons the admins give for not including Ren tags is quite frankly, really, really dumb. We have two sets of special snowflake Witch tags right now, but somehow Ren tags would be "niche". Worse, not having Ren tags has the added effect of de-legitimizing the Knights of Ren on the board. It's hard for us to establish the Knights as a unique branch of Force Users when the admins are doing everything they can to undermine this effort. Their decision continues to hurt us by adding to the confusion, where people now associate the Ren as just a special group of Sith, which they aren't.
But anyway.
All of the options suck, quite frankly. But "Dark Jedi" comes the closest to describing what the Knights of Ren are, because "Dark Jedi" is simply a catch-all term for any Force-user who uses the Dark Side. It's better than "Sith", because while the KoR have many similarities to the Sith, they are not Sith. Technically, to be a Sith one needs to actually be indoctrinated into the Sith cult, follow their rules, get a Darth name, etc., which the Knights of Ren do not. Therefore it would be a misnomer to call them Sith. The "Witch" tags are similarly useless. The Ren aren't Witches of Dathomir or affiliated with them in any way, so there is no reason to use those tags, unless you like the names I guess.
