There seems to be an issue in which characters with common first names get grouped together, even when they are not the same character.

I'm going to use some Naylor characters for example...

The elizabeth tag is mainly elizabeth_black but there is also an elizabeth_black tag that has only one post in it, and there are posts other than the elizabeth from naylor in elizabeth...
So, I'm not sure if we should move all the elizabeth posts from naylor into elizabeth_black because she only becomes that after marriage, and you know outside information and shit like that....which kinda causes an issue...
The fisk vs. fisk_black tag doesn't seem to be a huge issue as we could just use the fisk_black tag.
There's also the beth tag....
I know you could just put jay_naylor+beth or something like that...but still, when you get to a name like bob or something...well....i dunno.

Adding in a qualifier that signifies who/what a character belongs to/is from in brackets after their first name if you don't know what their last name is works pretty well. See here

just add _(artistname) to the tag

Full names, if known, should always be tagged. It makes far more logical sense to do this than anything else.

If a shorter version of a name is tagged as well then... I guess that's okay? On one hand it makes searching easier which is a benefit to the general populace and searchability of information. On the other hand, it makes tagging harder. Input from others would be good on this point.

Presently there seems to be no actual rule for this sort of thing. Tagging techniques that are in use:

• Full Name: Artica_Sparkle, Sonic_The_Hedgehog, Freya_Crescent
• First Name Only: Krystal, Purgy, Mario (Some characters may only have a first name of course)
• Name_(relevant show / game / IP) Twilight_Sparkle_(mlp), Felicia_(DarkStalkers)
• Name_(FandomOwner / ArtSiteName) Jess_(Teckly), Tala_(SunTattooWolf)
• Name_("character") Puzzle_(character), Necrodrone_(character), Furball_(character)
