DIS: "Judgement" or "Judgment"?

[Jason Cobb]

Again, as a matter of style, should we prefer "Judgement" or "Judgment"? 
My spellchecker complains about the first one, and it appears that 
"Judgment" is more accepted as correct. The Rules use both, although 
they only use "Judgment" (no e) twice, that being in Rule 2479 
("Official Justice"), but that rule then immediately proceeds to use 
"Judgement" (with e) twice.

I don't really care which one is picked, I'd rather just have consistency.
