So I was looking at my avatar image and noticed that mace got turned into a character tag.

I'm guessing because of Mace from Dreamkeepers?

But a mace is also a weapon.
Dunno.

EDIT: Well, I put in general:mace and it cleared it up.

There don't seem to be many posts tagged with mace at the moment, could we sort the problem out quite quickly by splitting them into these?

general:mace
character:mace_(dreamkeepers)

Actually, that's already been done. There's only one dreamkeepers picture tagged as plain 'mace', and I was planning on fixing that.

Mace_(character)
mace_(weapon)
Mace_(dreamkeepers)
mace_(spray)

Problem solved....I think.

Could probably go with Pepper_spray instead of the spray one, and either the weapon, or character one isn't needed, depending on which is the "normal" tag.
Personally I go with weapon, so:
general:Mace (for the weapon)
mace_(dreamkeepers)
pepper_spray
and if there's other character(s) named mace:
mace_(character)

And yes, I know that mace and pepper spray are different things, but in an image they are virtually indistinguishable from each other.
