It appears translation for Swedish is 100% done, so yes, this is being nitpicky, but on a justified linguistic level :P
Given our date formatting preferences in Sweden, if all three and using hyphens, it's year-month-day, But if only day and month (with our without a slash), day goes before month! It was very confusing to read 12/9 in the Swedish language version in the Last Logged In section, and not read it out as the 12th of September... it ought to be 9/12, the 9th of December (the 12th month). Because typically if writing the / form, any yearly notation follows in four number format after that (whether it's actual or just presumed). So for the 9th of December it'd be: 9/12 (2010), when focus is on the date, as opposed to when year starts the notation.
At least for these sections (so far): Birthdate, Latest Visitors, Last Logged In
Född: December 14, 1988
Född: 14 December, 1988
LATEST VISITORS, eg
Firstname Lastname Okt 1
Firstname Lastname 1 Okt
LAST LOGGED IN ie
Is there any way this can be applied to the Swedish language version of Geni?
I suspect this is on a more pure code level that this needs tending to though, rather than actual translation.
