This Wiki allows both the overuse of the letter z and overuse of the letter u, allowing the user to type in the language that they are culturally orientated with. It says here that it's the same with commas and periods. So the question is:

Should this punctuation rule be applied like the 'u's and 'z's, or should it be just the American version? This is, after all, an American organisation/website, and there is a fine line between a spelling rule defined by nationality and a punctuation rule defined by nationality. Oxford dictionary accepts both British and American spellings, but I doubt the Oxford grammar guide (if that actually exists) allows punctuation to go on the outside.

Maybe the wiki needs to have a discussion about this?
